WGET(1)  				     GNU Wget					    WGET(1) 

NAME
       Wget - The non-interactive network downloader.

SYNOPSIS
       wget [option]... [URL]...

DESCRIPTION
       GNU Wget is a free utility for non-interactive download of files from the Web.  It
       supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.

       Wget is non-interactive, meaning that it can work in the background, while the user is not
       logged on.  This allows you to start a retrieval and disconnect from the system, letting
       Wget finish the work.  By contrast, most of the Web browsers require constant user's
       presence, which can be a great hindrance when transferring a lot of data.

       Wget can follow links in HTML, XHTML, and CSS pages, to create local versions of remote
       web sites, fully recreating the directory structure of the original site.  This is
       sometimes referred to as "recursive downloading."  While doing that, Wget respects the
       Robot Exclusion Standard (/robots.txt).	Wget can be instructed to convert the links in
       downloaded files to point at the local files, for offline viewing.

       Wget has been designed for robustness over slow or unstable network connections; if a
       download fails due to a network problem, it will keep retrying until the whole file has
       been retrieved.	If the server supports regetting, it will instruct the server to continue
       the download from where it left off.

OPTIONS
   Option Syntax
       Since Wget uses GNU getopt to process command-line arguments, every option has a long form
       along with the short one.  Long options are more convenient to remember, but take time to
       type.  You may freely mix different option styles, or specify options after the command-
       line arguments.	Thus you may write:

	       wget -r --tries=10 http://fly.srk.fer.hr/ -o log

       The space between the option accepting an argument and the argument may be omitted.
       Instead of -o log you can write -olog.

       You may put several options that do not require arguments together, like:

	       wget -drc <URL>

       This is completely equivalent to:

	       wget -d -r -c <URL>

       Since the options can be specified after the arguments, you may terminate them with --.
       So the following will try to download URL -x, reporting failure to log:

	       wget -o log -- -x

       The options that accept comma-separated lists all respect the convention that specifying
       an empty list clears its value.	This can be useful to clear the .wgetrc settings.  For
       instance, if your .wgetrc sets "exclude_directories" to /cgi-bin, the following example
       will first reset it, and then set it to exclude /~nobody and /~somebody.  You can also
       clear the lists in .wgetrc.

	       wget -X " -X /~nobody,/~somebody

       Most options that do not accept arguments are boolean options, so named because their
       state can be captured with a yes-or-no ("boolean") variable.  For example, --follow-ftp
       tells Wget to follow FTP links from HTML files and, on the other hand, --no-glob tells it
       not to perform file globbing on FTP URLs.  A boolean option is either affirmative or
       negative (beginning with --no).	All such options share several properties.

       Unless stated otherwise, it is assumed that the default behavior is the opposite of what
       the option accomplishes.  For example, the documented existence of --follow-ftp assumes
       that the default is to not follow FTP links from HTML pages.

       Affirmative options can be negated by prepending the --no- to the option name; negative
       options can be negated by omitting the --no- prefix.  This might seem superfluous---if the
       default for an affirmative option is to not do something, then why provide a way to
       explicitly turn it off?	But the startup file may in fact change the default.  For
       instance, using "follow_ftp = on" in .wgetrc makes Wget follow FTP links by default, and
       using --no-follow-ftp is the only way to restore the factory default from the command
       line.

   Basic Startup Options
       -V
       --version
	   Display the version of Wget.

       -h
       --help
	   Print a help message describing all of Wget's command-line options.

       -b
       --background
	   Go to background immediately after startup.	If no output file is specified via the
	   -o, output is redirected to wget-log.

       -e command
       --execute command
	   Execute command as if it were a part of .wgetrc.  A command thus invoked will be
	   executed after the commands in .wgetrc, thus taking precedence over them.  If you need
	   to specify more than one wgetrc command, use multiple instances of -e.

   Logging and Input File Options
       -o logfile
       --output-file=logfile
	   Log all messages to logfile.  The messages are normally reported to standard error.

       -a logfile
       --append-output=logfile
	   Append to logfile.  This is the same as -o, only it appends to logfile instead of
	   overwriting the old log file.  If logfile does not exist, a new file is created.

       -d
       --debug
	   Turn on debug output, meaning various information important to the developers of Wget
	   if it does not work properly.  Your system administrator may have chosen to compile
	   Wget without debug support, in which case -d will not work.	Please note that
	   compiling with debug support is always safe---Wget compiled with the debug support
	   will not print any debug info unless requested with -d.

       -q
       --quiet
	   Turn off Wget's output.

       -v
       --verbose
	   Turn on verbose output, with all the available data.  The default output is verbose.

       -nv
       --no-verbose
	   Turn off verbose without being completely quiet (use -q for that), which means that
	   error messages and basic information still get printed.

       -i file
       --input-file=file
	   Read URLs from a local or external file.  If - is specified as file, URLs are read
	   from the standard input.  (Use ./- to read from a file literally named -.)

	   If this function is used, no URLs need be present on the command line.  If there are
	   URLs both on the command line and in an input file, those on the command lines will be
	   the first ones to be retrieved.  If --force-html is not specified, then file should
	   consist of a series of URLs, one per line.

	   However, if you specify --force-html, the document will be regarded as html.  In that
	   case you may have problems with relative links, which you can solve either by adding
	   "<base href="url">" to the documents or by specifying --base=url on the command line.

	   If the file is an external one, the document will be automatically treated as html if
	   the Content-Type matches text/html.	Furthermore, the file's location will be
	   implicitly used as base href if none was specified.

       -F
       --force-html
	   When input is read from a file, force it to be treated as an HTML file.  This enables
	   you to retrieve relative links from existing HTML files on your local disk, by adding
	   "<base href="url">" to HTML, or using the --base command-line option.

       -B URL
       --base=URL
	   Resolves relative links using URL as the point of reference, when reading links from
	   an HTML file specified via the -i/--input-file option (together with --force-html, or
	   when the input file was fetched remotely from a server describing it as HTML). This is
	   equivalent to the presence of a "BASE" tag in the HTML input file, with URL as the
	   value for the "href" attribute.

	   For instance, if you specify http://foo/bar/a.html for URL, and Wget reads
	   ../baz/b.html from the input file, it would be resolved to http://foo/baz/b.html.

   Download Options
       --bind-address=ADDRESS
	   When making client TCP/IP connections, bind to ADDRESS on the local machine.  ADDRESS
	   may be specified as a hostname or IP address.  This option can be useful if your
	   machine is bound to multiple IPs.

       -t number
       --tries=number
	   Set number of retries to number.  Specify 0 or inf for infinite retrying.  The default
	   is to retry 20 times, with the exception of fatal errors like "connection refused" or
	   "not found" (404), which are not retried.

       -O file
       --output-document=file
	   The documents will not be written to the appropriate files, but all will be
	   concatenated together and written to file.  If - is used as file, documents will be
	   printed to standard output, disabling link conversion.  (Use ./- to print to a file
	   literally named -.)

	   Use of -O is not intended to mean simply "use the name file instead of the one in the
	   URL;" rather, it is analogous to shell redirection: wget -O file http://foo is
	   intended to work like wget -O - http://foo > file; file will be truncated immediately,
	   and all downloaded content will be written there.

	   For this reason, -N (for timestamp-checking) is not supported in combination with -O:
	   since file is always newly created, it will always have a very new timestamp. A
	   warning will be issued if this combination is used.

	   Similarly, using -r or -p with -O may not work as you expect: Wget won't just download
	   the first file to file and then download the rest to their normal names: all
	   downloaded content will be placed in file. This was disabled in version 1.11, but has
	   been reinstated (with a warning) in 1.11.2, as there are some cases where this
	   behavior can actually have some use.

	   Note that a combination with -k is only permitted when downloading a single document,
	   as in that case it will just convert all relative URIs to external ones; -k makes no
	   sense for multiple URIs when they're all being downloaded to a single file.

       -nc
       --no-clobber
	   If a file is downloaded more than once in the same directory, Wget's behavior depends
	   on a few options, including -nc.  In certain cases, the local file will be clobbered,
	   or overwritten, upon repeated download.  In other cases it will be preserved.

	   When running Wget without -N, -nc, -r, or -p, downloading the same file in the same
	   directory will result in the original copy of file being preserved and the second copy
	   being named file.1.	If that file is downloaded yet again, the third copy will be
	   named file.2, and so on.  (This is also the behavior with -nd, even if -r or -p are in
	   effect.)  When -nc is specified, this behavior is suppressed, and Wget will refuse to
	   download newer copies of file.  Therefore, ""no-clobber"" is actually a misnomer in
	   this mode---it's not clobbering that's prevented (as the numeric suffixes were already
	   preventing clobbering), but rather the multiple version saving that's prevented.

	   When running Wget with -r or -p, but without -N, -nd, or -nc, re-downloading a file
	   will result in the new copy simply overwriting the old.  Adding -nc will prevent this
	   behavior, instead causing the original version to be preserved and any newer copies on
	   the server to be ignored.

	   When running Wget with -N, with or without -r or -p, the decision as to whether or not
	   to download a newer copy of a file depends on the local and remote timestamp and size
	   of the file.  -nc may not be specified at the same time as -N.

	   Note that when -nc is specified, files with the suffixes .html or .htm will be loaded
	   from the local disk and parsed as if they had been retrieved from the Web.

       -c
       --continue
	   Continue getting a partially-downloaded file.  This is useful when you want to finish
	   up a download started by a previous instance of Wget, or by another program.  For
	   instance:

		   wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z

	   If there is a file named ls-lR.Z in the current directory, Wget will assume that it is
	   the first portion of the remote file, and will ask the server to continue the
	   retrieval from an offset equal to the length of the local file.

	   Note that you don't need to specify this option if you just want the current
	   invocation of Wget to retry downloading a file should the connection be lost midway
	   through.  This is the default behavior.  -c only affects resumption of downloads
	   started prior to this invocation of Wget, and whose local files are still sitting
	   around.

	   Without -c, the previous example would just download the remote file to ls-lR.Z.1,
	   leaving the truncated ls-lR.Z file alone.

	   Beginning with Wget 1.7, if you use -c on a non-empty file, and it turns out that the
	   server does not support continued downloading, Wget will refuse to start the download
	   from scratch, which would effectively ruin existing contents.  If you really want the
	   download to start from scratch, remove the file.

	   Also beginning with Wget 1.7, if you use -c on a file which is of equal size as the
	   one on the server, Wget will refuse to download the file and print an explanatory
	   message.  The same happens when the file is smaller on the server than locally
	   (presumably because it was changed on the server since your last download
	   attempt)---because "continuing" is not meaningful, no download occurs.

	   On the other side of the coin, while using -c, any file that's bigger on the server
	   than locally will be considered an incomplete download and only "(length(remote) -
	   length(local))" bytes will be downloaded and tacked onto the end of the local file.
	   This behavior can be desirable in certain cases---for instance, you can use wget -c to
	   download just the new portion that's been appended to a data collection or log file.

	   However, if the file is bigger on the server because it's been changed, as opposed to
	   just appended to, you'll end up with a garbled file.  Wget has no way of verifying
	   that the local file is really a valid prefix of the remote file.  You need to be
	   especially careful of this when using -c in conjunction with -r, since every file will
	   be considered as an "incomplete download" candidate.

	   Another instance where you'll get a garbled file if you try to use -c is if you have a
	   lame HTTP proxy that inserts a "transfer interrupted" string into the local file.  In
	   the future a "rollback" option may be added to deal with this case.

	   Note that -c only works with FTP servers and with HTTP servers that support the
	   "Range" header.

       --progress=type
	   Select the type of the progress indicator you wish to use.  Legal indicators are "dot"
	   and "bar".

	   The "bar" indicator is used by default.  It draws an ASCII progress bar graphics
	   (a.k.a "thermometer" display) indicating the status of retrieval.  If the output is
	   not a TTY, the "dot" bar will be used by default.

	   Use --progress=dot to switch to the "dot" display.  It traces the retrieval by
	   printing dots on the screen, each dot representing a fixed amount of downloaded data.

	   When using the dotted retrieval, you may also set the style by specifying the type as
	   dot:style.  Different styles assign different meaning to one dot.  With the "default"
	   style each dot represents 1K, there are ten dots in a cluster and 50 dots in a line.
	   The "binary" style has a more "computer"-like orientation---8K dots, 16-dots clusters
	   and 48 dots per line (which makes for 384K lines).  The "mega" style is suitable for
	   downloading very large files---each dot represents 64K retrieved, there are eight dots
	   in a cluster, and 48 dots on each line (so each line contains 3M).

	   Note that you can set the default style using the "progress" command in .wgetrc.  That
	   setting may be overridden from the command line.  The exception is that, when the
	   output is not a TTY, the "dot" progress will be favored over "bar".	To force the bar
	   output, use --progress=bar:force.

       -N
       --timestamping
	   Turn on time-stamping.

       -S
       --server-response
	   Print the headers sent by HTTP servers and responses sent by FTP servers.

       --spider
	   When invoked with this option, Wget will behave as a Web spider, which means that it
	   will not download the pages, just check that they are there.  For example, you can use
	   Wget to check your bookmarks:

		   wget --spider --force-html -i bookmarks.html

	   This feature needs much more work for Wget to get close to the functionality of real
	   web spiders.

       -T seconds
       --timeout=seconds
	   Set the network timeout to seconds seconds.	This is equivalent to specifying
	   --dns-timeout, --connect-timeout, and --read-timeout, all at the same time.

	   When interacting with the network, Wget can check for timeout and abort the operation
	   if it takes too long.  This prevents anomalies like hanging reads and infinite
	   connects.  The only timeout enabled by default is a 900-second read timeout.  Setting
	   a timeout to 0 disables it altogether.  Unless you know what you are doing, it is best
	   not to change the default timeout settings.

	   All timeout-related options accept decimal values, as well as subsecond values.  For
	   example, 0.1 seconds is a legal (though unwise) choice of timeout.  Subsecond timeouts
	   are useful for checking server response times or for testing network latency.

       --dns-timeout=seconds
	   Set the DNS lookup timeout to seconds seconds.  DNS lookups that don't complete within
	   the specified time will fail.  By default, there is no timeout on DNS lookups, other
	   than that implemented by system libraries.

       --connect-timeout=seconds
	   Set the connect timeout to seconds seconds.	TCP connections that take longer to
	   establish will be aborted.  By default, there is no connect timeout, other than that
	   implemented by system libraries.

       --read-timeout=seconds
	   Set the read (and write) timeout to seconds seconds.  The "time" of this timeout
	   refers to idle time: if, at any point in the download, no data is received for more
	   than the specified number of seconds, reading fails and the download is restarted.
	   This option does not directly affect the duration of the entire download.

	   Of course, the remote server may choose to terminate the connection sooner than this
	   option requires.  The default read timeout is 900 seconds.

       --limit-rate=amount
	   Limit the download speed to amount bytes per second.  Amount may be expressed in
	   bytes, kilobytes with the k suffix, or megabytes with the m suffix.	For example,
	   --limit-rate=20k will limit the retrieval rate to 20KB/s.  This is useful when, for
	   whatever reason, you don't want Wget to consume the entire available bandwidth.

	   This option allows the use of decimal numbers, usually in conjunction with power
	   suffixes; for example, --limit-rate=2.5k is a legal value.

	   Note that Wget implements the limiting by sleeping the appropriate amount of time
	   after a network read that took less time than specified by the rate.  Eventually this
	   strategy causes the TCP transfer to slow down to approximately the specified rate.
	   However, it may take some time for this balance to be achieved, so don't be surprised
	   if limiting the rate doesn't work well with very small files.

       -w seconds
       --wait=seconds
	   Wait the specified number of seconds between the retrievals.  Use of this option is
	   recommended, as it lightens the server load by making the requests less frequent.
	   Instead of in seconds, the time can be specified in minutes using the "m" suffix, in
	   hours using "h" suffix, or in days using "d" suffix.

	   Specifying a large value for this option is useful if the network or the destination
	   host is down, so that Wget can wait long enough to reasonably expect the network error
	   to be fixed before the retry.  The waiting interval specified by this function is
	   influenced by "--random-wait", which see.

       --waitretry=seconds
	   If you don't want Wget to wait between every retrieval, but only between retries of
	   failed downloads, you can use this option.  Wget will use linear backoff, waiting 1
	   second after the first failure on a given file, then waiting 2 seconds after the
	   second failure on that file, up to the maximum number of seconds you specify.
	   Therefore, a value of 10 will actually make Wget wait up to (1 + 2 + ... + 10) = 55
	   seconds per file.

	   By default, Wget will assume a value of 10 seconds.

       --random-wait
	   Some web sites may perform log analysis to identify retrieval programs such as Wget by
	   looking for statistically significant similarities in the time between requests. This
	   option causes the time between requests to vary between 0.5 and 1.5 * wait seconds,
	   where wait was specified using the --wait option, in order to mask Wget's presence
	   from such analysis.

	   A 2001 article in a publication devoted to development on a popular consumer platform
	   provided code to perform this analysis on the fly.  Its author suggested blocking at
	   the class C address level to ensure automated retrieval programs were blocked despite
	   changing DHCP-supplied addresses.

	   The --random-wait option was inspired by this ill-advised recommendation to block many
	   unrelated users from a web site due to the actions of one.

       --no-proxy
	   Don't use proxies, even if the appropriate *_proxy environment variable is defined.

       -Q quota
       --quota=quota
	   Specify download quota for automatic retrievals.  The value can be specified in bytes
	   (default), kilobytes (with k suffix), or megabytes (with m suffix).

	   Note that quota will never affect downloading a single file.  So if you specify wget
	   -Q10k ftp://wuarchive.wustl.edu/ls-lR.gz, all of the ls-lR.gz will be downloaded.  The
	   same goes even when several URLs are specified on the command-line.	However, quota is
	   respected when retrieving either recursively, or from an input file.  Thus you may
	   safely type wget -Q2m -i sites---download will be aborted when the quota is exceeded.

	   Setting quota to 0 or to inf unlimits the download quota.

       --no-dns-cache
	   Turn off caching of DNS lookups.  Normally, Wget remembers the IP addresses it looked
	   up from DNS so it doesn't have to repeatedly contact the DNS server for the same
	   (typically small) set of hosts it retrieves from.  This cache exists in memory only; a
	   new Wget run will contact DNS again.

	   However, it has been reported that in some situations it is not desirable to cache
	   host names, even for the duration of a short-running application like Wget.	With this
	   option Wget issues a new DNS lookup (more precisely, a new call to "gethostbyname" or
	   "getaddrinfo") each time it makes a new connection.	Please note that this option will
	   not affect caching that might be performed by the resolving library or by an external
	   caching layer, such as NSCD.

	   If you don't understand exactly what this option does, you probably won't need it.

       --restrict-file-names=modes
	   Change which characters found in remote URLs must be escaped during generation of
	   local filenames.  Characters that are restricted by this option are escaped, i.e.
	   replaced with %HH, where HH is the hexadecimal number that corresponds to the
	   restricted character. This option may also be used to force all alphabetical cases to
	   be either lower- or uppercase.

	   By default, Wget escapes the characters that are not valid or safe as part of file
	   names on your operating system, as well as control characters that are typically
	   unprintable.  This option is useful for changing these defaults, perhaps because you
	   are downloading to a non-native partition, or because you want to disable escaping of
	   the control characters, or you want to further restrict characters to only those in
	   the ASCII range of values.

	   The modes are a comma-separated set of text values. The acceptable values are unix,
	   windows, nocontrol, ascii, lowercase, and uppercase. The values unix and windows are
	   mutually exclusive (one will override the other), as are lowercase and uppercase.
	   Those last are special cases, as they do not change the set of characters that would
	   be escaped, but rather force local file paths to be converted either to lower- or
	   uppercase.

	   When "unix" is specified, Wget escapes the character / and the control characters in
	   the ranges 0--31 and 128--159.  This is the default on Unix-like operating systems.

	   When "windows" is given, Wget escapes the characters \, |, /, :, ?, ", *, <, >, and
	   the control characters in the ranges 0--31 and 128--159.  In addition to this, Wget in
	   Windows mode uses + instead of : to separate host and port in local file names, and
	   uses @ instead of ? to separate the query portion of the file name from the rest.
	   Therefore, a URL that would be saved as www.xemacs.org:4300/search.pl?input=blah in
	   Unix mode would be saved as www.xemacs.org+4300/search.pl@input=blah in Windows mode.
	   This mode is the default on Windows.

	   If you specify nocontrol, then the escaping of the control characters is also switched
	   off. This option may make sense when you are downloading URLs whose names contain
	   UTF-8 characters, on a system which can save and display filenames in UTF-8 (some
	   possible byte values used in UTF-8 byte sequences fall in the range of values
	   designated by Wget as "controls").

	   The ascii mode is used to specify that any bytes whose values are outside the range of
	   ASCII characters (that is, greater than 127) shall be escaped. This can be useful when
	   saving filenames whose encoding does not match the one used locally.

       -4
       --inet4-only
       -6
       --inet6-only
	   Force connecting to IPv4 or IPv6 addresses.	With --inet4-only or -4, Wget will only
	   connect to IPv4 hosts, ignoring AAAA records in DNS, and refusing to connect to IPv6
	   addresses specified in URLs.  Conversely, with --inet6-only or -6, Wget will only
	   connect to IPv6 hosts and ignore A records and IPv4 addresses.

	   Neither options should be needed normally.  By default, an IPv6-aware Wget will use
	   the address family specified by the host's DNS record.  If the DNS responds with both
	   IPv4 and IPv6 addresses, Wget will try them in sequence until it finds one it can
	   connect to.	(Also see "--prefer-family" option described below.)

	   These options can be used to deliberately force the use of IPv4 or IPv6 address
	   families on dual family systems, usually to aid debugging or to deal with broken
	   network configuration.  Only one of --inet6-only and --inet4-only may be specified at
	   the same time.  Neither option is available in Wget compiled without IPv6 support.

       --prefer-family=none/IPv4/IPv6
	   When given a choice of several addresses, connect to the addresses with specified
	   address family first.  The address order returned by DNS is used without change by
	   default.

	   This avoids spurious errors and connect attempts when accessing hosts that resolve to
	   both IPv6 and IPv4 addresses from IPv4 networks.  For example, www.kame.net resolves
	   to 2001:200:0:8002:203:47ff:fea5:3085 and to 203.178.141.194.  When the preferred
	   family is "IPv4", the IPv4 address is used first; when the preferred family is "IPv6",
	   the IPv6 address is used first; if the specified value is "none", the address order
	   returned by DNS is used without change.

	   Unlike -4 and -6, this option doesn't inhibit access to any address family, it only
	   changes the order in which the addresses are accessed.  Also note that the reordering
	   performed by this option is stable---it doesn't affect order of addresses of the same
	   family.  That is, the relative order of all IPv4 addresses and of all IPv6 addresses
	   remains intact in all cases.

       --retry-connrefused
	   Consider "connection refused" a transient error and try again.  Normally Wget gives up
	   on a URL when it is unable to connect to the site because failure to connect is taken
	   as a sign that the server is not running at all and that retries would not help.  This
	   option is for mirroring unreliable sites whose servers tend to disappear for short
	   periods of time.

       --user=user
       --password=password
	   Specify the username user and password password for both FTP and HTTP file retrieval.
	   These parameters can be overridden using the --ftp-user and --ftp-password options for
	   FTP connections and the --http-user and --http-password options for HTTP connections.

       --ask-password
	   Prompt for a password for each connection established. Cannot be specified when
	   --password is being used, because they are mutually exclusive.

       --no-iri
	   Turn off internationalized URI (IRI) support. Use --iri to turn it on. IRI support is
	   activated by default.

	   You can set the default state of IRI support using the "iri" command in .wgetrc. That
	   setting may be overridden from the command line.

       --local-encoding=encoding
	   Force Wget to use encoding as the default system encoding. That affects how Wget
	   converts URLs specified as arguments from locale to UTF-8 for IRI support.

	   Wget use the function "nl_langinfo()" and then the "CHARSET" environment variable to
	   get the locale. If it fails, ASCII is used.

	   You can set the default local encoding using the "local_encoding" command in .wgetrc.
	   That setting may be overridden from the command line.

       --remote-encoding=encoding
	   Force Wget to use encoding as the default remote server encoding.  That affects how
	   Wget converts URIs found in files from remote encoding to UTF-8 during a recursive
	   fetch. This options is only useful for IRI support, for the interpretation of non-
	   ASCII characters.

	   For HTTP, remote encoding can be found in HTTP "Content-Type" header and in HTML
	   "Content-Type http-equiv" meta tag.

	   You can set the default encoding using the "remoteencoding" command in .wgetrc. That
	   setting may be overridden from the command line.

   Directory Options
       -nd
       --no-directories
	   Do not create a hierarchy of directories when retrieving recursively.  With this
	   option turned on, all files will get saved to the current directory, without
	   clobbering (if a name shows up more than once, the filenames will get extensions .n).

       -x
       --force-directories
	   The opposite of -nd---create a hierarchy of directories, even if one would not have
	   been created otherwise.  E.g. wget -x http://fly.srk.fer.hr/robots.txt will save the
	   downloaded file to fly.srk.fer.hr/robots.txt.

       -nH
       --no-host-directories
	   Disable generation of host-prefixed directories.  By default, invoking Wget with -r
	   http://fly.srk.fer.hr/ will create a structure of directories beginning with
	   fly.srk.fer.hr/.  This option disables such behavior.

       --protocol-directories
	   Use the protocol name as a directory component of local file names.	For example, with
	   this option, wget -r http://host will save to http/host/... rather than just to
	   host/....

       --cut-dirs=number
	   Ignore number directory components.	This is useful for getting a fine-grained control
	   over the directory where recursive retrieval will be saved.

	   Take, for example, the directory at ftp://ftp.xemacs.org/pub/xemacs/.  If you retrieve
	   it with -r, it will be saved locally under ftp.xemacs.org/pub/xemacs/.  While the -nH
	   option can remove the ftp.xemacs.org/ part, you are still stuck with pub/xemacs.  This
	   is where --cut-dirs comes in handy; it makes Wget not "see" number remote directory
	   components.	Here are several examples of how --cut-dirs option works.

		   No options	     -> ftp.xemacs.org/pub/xemacs/
		   -nH		     -> pub/xemacs/
		   -nH --cut-dirs=1  -> xemacs/
		   -nH --cut-dirs=2  -> .

		   --cut-dirs=1      -> ftp.xemacs.org/xemacs/
		   ...

	   If you just want to get rid of the directory structure, this option is similar to a
	   combination of -nd and -P.  However, unlike -nd, --cut-dirs does not lose with
	   subdirectories---for instance, with -nH --cut-dirs=1, a beta/ subdirectory will be
	   placed to xemacs/beta, as one would expect.

       -P prefix
       --directory-prefix=prefix
	   Set directory prefix to prefix.  The directory prefix is the directory where all other
	   files and subdirectories will be saved to, i.e. the top of the retrieval tree.  The
	   default is . (the current directory).

   HTTP Options
       --default-page=name
	   Use name as the default file name when it isn't known (i.e., for URLs that end in a
	   slash), instead of index.html.

       -E
       --adjust-extension
	   If a file of type application/xhtml+xml or text/html is downloaded and the URL does
	   not end with the regexp \.[Hh][Tt][Mm][Ll]?, this option will cause the suffix .html
	   to be appended to the local filename.  This is useful, for instance, when you're
	   mirroring a remote site that uses .asp pages, but you want the mirrored pages to be
	   viewable on your stock Apache server.  Another good use for this is when you're
	   downloading CGI-generated materials.  A URL like http://site.com/article.cgi?25 will
	   be saved as article.cgi?25.html.

	   Note that filenames changed in this way will be re-downloaded every time you re-mirror
	   a site, because Wget can't tell that the local X.html file corresponds to remote URL X
	   (since it doesn't yet know that the URL produces output of type text/html or
	   application/xhtml+xml.  To prevent this re-downloading, you must use -k and -K so that
	   the original version of the file will be saved as X.orig.

	   As of version 1.12, Wget will also ensure that any downloaded files of type text/css
	   end in the suffix .css, and the option was renamed from --html-extension, to better
	   reflect its new behavior. The old option name is still acceptable, but should now be
	   considered deprecated.

	   At some point in the future, this option may well be expanded to include suffixes for
	   other types of content, including content types that are not parsed by Wget.

       --http-user=user
       --http-password=password
	   Specify the username user and password password on an HTTP server.  According to the
	   type of the challenge, Wget will encode them using either the "basic" (insecure), the
	   "digest", or the Windows "NTLM" authentication scheme.

	   Another way to specify username and password is in the URL itself.  Either method
	   reveals your password to anyone who bothers to run "ps".  To prevent the passwords
	   from being seen, store them in .wgetrc or .netrc, and make sure to protect those files
	   from other users with "chmod".  If the passwords are really important, do not leave
	   them lying in those files either---edit the files and delete them after Wget has
	   started the download.

       --no-http-keep-alive
	   Turn off the "keep-alive" feature for HTTP downloads.  Normally, Wget asks the server
	   to keep the connection open so that, when you download more than one document from the
	   same server, they get transferred over the same TCP connection.  This saves time and
	   at the same time reduces the load on the server.

	   This option is useful when, for some reason, persistent (keep-alive) connections don't
	   work for you, for example due to a server bug or due to the inability of server-side
	   scripts to cope with the connections.

       --no-cache
	   Disable server-side cache.  In this case, Wget will send the remote server an
	   appropriate directive (Pragma: no-cache) to get the file from the remote service,
	   rather than returning the cached version.  This is especially useful for retrieving
	   and flushing out-of-date documents on proxy servers.

	   Caching is allowed by default.

       --no-cookies
	   Disable the use of cookies.	Cookies are a mechanism for maintaining server-side
	   state.  The server sends the client a cookie using the "Set-Cookie" header, and the
	   client responds with the same cookie upon further requests.	Since cookies allow the
	   server owners to keep track of visitors and for sites to exchange this information,
	   some consider them a breach of privacy.  The default is to use cookies; however,
	   storing cookies is not on by default.

       --load-cookies file
	   Load cookies from file before the first HTTP retrieval.  file is a textual file in the
	   format originally used by Netscape's cookies.txt file.

	   You will typically use this option when mirroring sites that require that you be
	   logged in to access some or all of their content.  The login process typically works
	   by the web server issuing an HTTP cookie upon receiving and verifying your
	   credentials.  The cookie is then resent by the browser when accessing that part of the
	   site, and so proves your identity.

	   Mirroring such a site requires Wget to send the same cookies your browser sends when
	   communicating with the site.  This is achieved by --load-cookies---simply point Wget
	   to the location of the cookies.txt file, and it will send the same cookies your
	   browser would send in the same situation.  Different browsers keep textual cookie
	   files in different locations:

	   Netscape 4.x.
	       The cookies are in ~/.netscape/cookies.txt.

	   Mozilla and Netscape 6.x.
	       Mozilla's cookie file is also named cookies.txt, located somewhere under
	       ~/.mozilla, in the directory of your profile.  The full path usually ends up
	       looking somewhat like ~/.mozilla/default/some-weird-string/cookies.txt.

	   Internet Explorer.
	       You can produce a cookie file Wget can use by using the File menu, Import and
	       Export, Export Cookies.	This has been tested with Internet Explorer 5; it is not
	       guaranteed to work with earlier versions.

	   Other browsers.
	       If you are using a different browser to create your cookies, --load-cookies will
	       only work if you can locate or produce a cookie file in the Netscape format that
	       Wget expects.

	   If you cannot use --load-cookies, there might still be an alternative.  If your
	   browser supports a "cookie manager", you can use it to view the cookies used when
	   accessing the site you're mirroring.  Write down the name and value of the cookie, and
	   manually instruct Wget to send those cookies, bypassing the "official" cookie support:

		   wget --no-cookies --header "Cookie: <name>=<value>"

       --save-cookies file
	   Save cookies to file before exiting.  This will not save cookies that have expired or
	   that have no expiry time (so-called "session cookies"), but also see
	   --keep-session-cookies.

       --keep-session-cookies
	   When specified, causes --save-cookies to also save session cookies.	Session cookies
	   are normally not saved because they are meant to be kept in memory and forgotten when
	   you exit the browser.  Saving them is useful on sites that require you to log in or to
	   visit the home page before you can access some pages.  With this option, multiple Wget
	   runs are considered a single browser session as far as the site is concerned.

	   Since the cookie file format does not normally carry session cookies, Wget marks them
	   with an expiry timestamp of 0.  Wget's --load-cookies recognizes those as session
	   cookies, but it might confuse other browsers.  Also note that cookies so loaded will
	   be treated as other session cookies, which means that if you want --save-cookies to
	   preserve them again, you must use --keep-session-cookies again.

       --ignore-length
	   Unfortunately, some HTTP servers (CGI programs, to be more precise) send out bogus
	   "Content-Length" headers, which makes Wget go wild, as it thinks not all the document
	   was retrieved.  You can spot this syndrome if Wget retries getting the same document
	   again and again, each time claiming that the (otherwise normal) connection has closed
	   on the very same byte.

	   With this option, Wget will ignore the "Content-Length" header---as if it never
	   existed.

       --header=header-line
	   Send header-line along with the rest of the headers in each HTTP request.  The
	   supplied header is sent as-is, which means it must contain name and value separated by
	   colon, and must not contain newlines.

	   You may define more than one additional header by specifying --header more than once.

		   wget --header='Accept-Charset: iso-8859-2' \
			--header='Accept-Language: hr'	      \
			  http://fly.srk.fer.hr/

	   Specification of an empty string as the header value will clear all previous user-
	   defined headers.

	   As of Wget 1.10, this option can be used to override headers otherwise generated
	   automatically.  This example instructs Wget to connect to localhost, but to specify
	   foo.bar in the "Host" header:

		   wget --header="Host: foo.bar" http://localhost/

	   In versions of Wget prior to 1.10 such use of --header caused sending of duplicate
	   headers.

       --max-redirect=number
	   Specifies the maximum number of redirections to follow for a resource.  The default is
	   20, which is usually far more than necessary. However, on those occasions where you
	   want to allow more (or fewer), this is the option to use.

       --proxy-user=user
       --proxy-password=password
	   Specify the username user and password password for authentication on a proxy server.
	   Wget will encode them using the "basic" authentication scheme.

	   Security considerations similar to those with --http-password pertain here as well.

       --referer=url
	   Include `Referer: url' header in HTTP request.  Useful for retrieving documents with
	   server-side processing that assume they are always being retrieved by interactive web
	   browsers and only come out properly when Referer is set to one of the pages that point
	   to them.

       --save-headers
	   Save the headers sent by the HTTP server to the file, preceding the actual contents,
	   with an empty line as the separator.

       -U agent-string
       --user-agent=agent-string
	   Identify as agent-string to the HTTP server.

	   The HTTP protocol allows the clients to identify themselves using a "User-Agent"
	   header field.  This enables distinguishing the WWW software, usually for statistical
	   purposes or for tracing of protocol violations.  Wget normally identifies as
	   Wget/version, version being the current version number of Wget.

	   However, some sites have been known to impose the policy of tailoring the output
	   according to the "User-Agent"-supplied information.	While this is not such a bad idea
	   in theory, it has been abused by servers denying information to clients other than
	   (historically) Netscape or, more frequently, Microsoft Internet Explorer.  This option
	   allows you to change the "User-Agent" line issued by Wget.  Use of this option is
	   discouraged, unless you really know what you are doing.

	   Specifying empty user agent with --user-agent="" instructs Wget not to send the
	   "User-Agent" header in HTTP requests.

       --post-data=string
       --post-file=file
	   Use POST as the method for all HTTP requests and send the specified data in the
	   request body.  --post-data sends string as data, whereas --post-file sends the
	   contents of file.  Other than that, they work in exactly the same way. In particular,
	   they both expect content of the form "key1=value1&key2=value2", with percent-encoding
	   for special characters; the only difference is that one expects its content as a
	   command-line parameter and the other accepts its content from a file. In particular,
	   --post-file is not for transmitting files as form attachments: those must appear as
	   "key=value" data (with appropriate percent-coding) just like everything else. Wget
	   does not currently support "multipart/form-data" for transmitting POST data; only
	   "application/x-www-form-urlencoded". Only one of --post-data and --post-file should be
	   specified.

	   Please be aware that Wget needs to know the size of the POST data in advance.
	   Therefore the argument to "--post-file" must be a regular file; specifying a FIFO or
	   something like /dev/stdin won't work.  It's not quite clear how to work around this
	   limitation inherent in HTTP/1.0.  Although HTTP/1.1 introduces chunked transfer that
	   doesn't require knowing the request length in advance, a client can't use chunked
	   unless it knows it's talking to an HTTP/1.1 server.	And it can't know that until it
	   receives a response, which in turn requires the request to have been completed -- a
	   chicken-and-egg problem.

	   Note: if Wget is redirected after the POST request is completed, it will not send the
	   POST data to the redirected URL.  This is because URLs that process POST often respond
	   with a redirection to a regular page, which does not desire or accept POST.	It is not
	   completely clear that this behavior is optimal; if it doesn't work out, it might be
	   changed in the future.

	   This example shows how to log to a server using POST and then proceed to download the
	   desired pages, presumably only accessible to authorized users:

		   # Log in to the server.  This can be done only once.
		   wget --save-cookies cookies.txt \
			--post-data 'user=foo&password=bar' \
			http://server.com/auth.php

		   # Now grab the page or pages we care about.
		   wget --load-cookies cookies.txt \
			-p http://server.com/interesting/article.php

	   If the server is using session cookies to track user authentication, the above will
	   not work because --save-cookies will not save them (and neither will browsers) and the
	   cookies.txt file will be empty.  In that case use --keep-session-cookies along with
	   --save-cookies to force saving of session cookies.

       --content-disposition
	   If this is set to on, experimental (not fully-functional) support for
	   "Content-Disposition" headers is enabled. This can currently result in extra round-
	   trips to the server for a "HEAD" request, and is known to suffer from a few bugs,
	   which is why it is not currently enabled by default.

	   This option is useful for some file-downloading CGI programs that use
	   "Content-Disposition" headers to describe what the name of a downloaded file should
	   be.

       --trust-server-names
	   If this is set to on, on a redirect the last component of the redirection URL will be
	   used as the local file name.  By default it is used the last component in the original
	   URL.

       --auth-no-challenge
	   If this option is given, Wget will send Basic HTTP authentication information
	   (plaintext username and password) for all requests, just like Wget 1.10.2 and prior
	   did by default.

	   Use of this option is not recommended, and is intended only to support some few
	   obscure servers, which never send HTTP authentication challenges, but accept
	   unsolicited auth info, say, in addition to form-based authentication.

   HTTPS (SSL/TLS) Options
       To support encrypted HTTP (HTTPS) downloads, Wget must be compiled with an external SSL
       library, currently OpenSSL.  If Wget is compiled without SSL support, none of these
       options are available.

       --secure-protocol=protocol
	   Choose the secure protocol to be used.  Legal values are auto, SSLv2, SSLv3, and
	   TLSv1.  If auto is used, the SSL library is given the liberty of choosing the
	   appropriate protocol automatically, which is achieved by sending an SSLv2 greeting and
	   announcing support for SSLv3 and TLSv1.  This is the default.

	   Specifying SSLv2, SSLv3, or TLSv1 forces the use of the corresponding protocol.  This
	   is useful when talking to old and buggy SSL server implementations that make it hard
	   for OpenSSL to choose the correct protocol version.	Fortunately, such servers are
	   quite rare.

	   Note that SSLv2 may not be available in your version of Wget, because it has been
	   deprecated since 1996.

       --no-check-certificate
	   Don't check the server certificate against the available certificate authorities.
	   Also don't require the URL host name to match the common name presented by the
	   certificate.

	   As of Wget 1.10, the default is to verify the server's certificate against the
	   recognized certificate authorities, breaking the SSL handshake and aborting the
	   download if the verification fails.	Although this provides more secure downloads, it
	   does break interoperability with some sites that worked with previous Wget versions,
	   particularly those using self-signed, expired, or otherwise invalid certificates.
	   This option forces an "insecure" mode of operation that turns the certificate
	   verification errors into warnings and allows you to proceed.

	   If you encounter "certificate verification" errors or ones saying that "common name
	   doesn't match requested host name", you can use this option to bypass the verification
	   and proceed with the download.  Only use this option if you are otherwise convinced of
	   the site's authenticity, or if you really don't care about the validity of its
	   certificate.  It is almost always a bad idea not to check the certificates when
	   transmitting confidential or important data.

       --certificate=file
	   Use the client certificate stored in file.  This is needed for servers that are
	   configured to require certificates from the clients that connect to them.  Normally a
	   certificate is not required and this switch is optional.

       --certificate-type=type
	   Specify the type of the client certificate.	Legal values are PEM (assumed by default)
	   and DER, also known as ASN1.

       --private-key=file
	   Read the private key from file.  This allows you to provide the private key in a file
	   separate from the certificate.

       --private-key-type=type
	   Specify the type of the private key.  Accepted values are PEM (the default) and DER.

       --ca-certificate=file
	   Use file as the file with the bundle of certificate authorities ("CA") to verify the
	   peers.  The certificates must be in PEM format.

	   Without this option Wget looks for CA certificates at the system-specified locations,
	   chosen at OpenSSL installation time.

       --ca-directory=directory
	   Specifies directory containing CA certificates in PEM format.  Each file contains one
	   CA certificate, and the file name is based on a hash value derived from the
	   certificate.  This is achieved by processing a certificate directory with the
	   "c_rehash" utility supplied with OpenSSL.  Using --ca-directory is more efficient than
	   --ca-certificate when many certificates are installed because it allows Wget to fetch
	   certificates on demand.

	   Without this option Wget looks for CA certificates at the system-specified locations,
	   chosen at OpenSSL installation time.

       --random-file=file
	   Use file as the source of random data for seeding the pseudo-random number generator
	   on systems without /dev/random.

	   On such systems the SSL library needs an external source of randomness to initialize.
	   Randomness may be provided by EGD (see --egd-file below) or read from an external
	   source specified by the user.  If this option is not specified, Wget looks for random
	   data in $RANDFILE or, if that is unset, in $HOME/.rnd.  If none of those are
	   available, it is likely that SSL encryption will not be usable.

	   If you're getting the "Could not seed OpenSSL PRNG; disabling SSL."	error, you should
	   provide random data using some of the methods described above.

       --egd-file=file
	   Use file as the EGD socket.	EGD stands for Entropy Gathering Daemon, a user-space
	   program that collects data from various unpredictable system sources and makes it
	   available to other programs that might need it.  Encryption software, such as the SSL
	   library, needs sources of non-repeating randomness to seed the random number generator
	   used to produce cryptographically strong keys.

	   OpenSSL allows the user to specify his own source of entropy using the "RAND_FILE"
	   environment variable.  If this variable is unset, or if the specified file does not
	   produce enough randomness, OpenSSL will read random data from EGD socket specified
	   using this option.

	   If this option is not specified (and the equivalent startup command is not used), EGD
	   is never contacted.	EGD is not needed on modern Unix systems that support
	   /dev/random.

   FTP Options
       --ftp-user=user
       --ftp-password=password
	   Specify the username user and password password on an FTP server.  Without this, or
	   the corresponding startup option, the password defaults to -wget@, normally used for
	   anonymous FTP.

	   Another way to specify username and password is in the URL itself.  Either method
	   reveals your password to anyone who bothers to run "ps".  To prevent the passwords
	   from being seen, store them in .wgetrc or .netrc, and make sure to protect those files
	   from other users with "chmod".  If the passwords are really important, do not leave
	   them lying in those files either---edit the files and delete them after Wget has
	   started the download.

       --no-remove-listing
	   Don't remove the temporary .listing files generated by FTP retrievals.  Normally,
	   these files contain the raw directory listings received from FTP servers.  Not
	   removing them can be useful for debugging purposes, or when you want to be able to
	   easily check on the contents of remote server directories (e.g. to verify that a
	   mirror you're running is complete).

	   Note that even though Wget writes to a known filename for this file, this is not a
	   security hole in the scenario of a user making .listing a symbolic link to /etc/passwd
	   or something and asking "root" to run Wget in his or her directory.	Depending on the
	   options used, either Wget will refuse to write to .listing, making the
	   globbing/recursion/time-stamping operation fail, or the symbolic link will be deleted
	   and replaced with the actual .listing file, or the listing will be written to a
	   .listing.number file.

	   Even though this situation isn't a problem, though, "root" should never run Wget in a
	   non-trusted user's directory.  A user could do something as simple as linking
	   index.html to /etc/passwd and asking "root" to run Wget with -N or -r so the file will
	   be overwritten.

       --no-glob
	   Turn off FTP globbing.  Globbing refers to the use of shell-like special characters
	   (wildcards), like *, ?, [ and ] to retrieve more than one file from the same directory
	   at once, like:

		   wget ftp://gnjilux.srk.fer.hr/*.msg

	   By default, globbing will be turned on if the URL contains a globbing character.  This
	   option may be used to turn globbing on or off permanently.

	   You may have to quote the URL to protect it from being expanded by your shell.
	   Globbing makes Wget look for a directory listing, which is system-specific.	This is
	   why it currently works only with Unix FTP servers (and the ones emulating Unix "ls"
	   output).

       --no-passive-ftp
	   Disable the use of the passive FTP transfer mode.  Passive FTP mandates that the
	   client connect to the server to establish the data connection rather than the other
	   way around.

	   If the machine is connected to the Internet directly, both passive and active FTP
	   should work equally well.  Behind most firewall and NAT configurations passive FTP has
	   a better chance of working.	However, in some rare firewall configurations, active FTP
	   actually works when passive FTP doesn't.  If you suspect this to be the case, use this
	   option, or set "passive_ftp=off" in your init file.

       --retr-symlinks
	   Usually, when retrieving FTP directories recursively and a symbolic link is
	   encountered, the linked-to file is not downloaded.  Instead, a matching symbolic link
	   is created on the local filesystem.	The pointed-to file will not be downloaded unless
	   this recursive retrieval would have encountered it separately and downloaded it
	   anyway.

	   When --retr-symlinks is specified, however, symbolic links are traversed and the
	   pointed-to files are retrieved.  At this time, this option does not cause Wget to
	   traverse symlinks to directories and recurse through them, but in the future it should
	   be enhanced to do this.

	   Note that when retrieving a file (not a directory) because it was specified on the
	   command-line, rather than because it was recursed to, this option has no effect.
	   Symbolic links are always traversed in this case.

   Recursive Retrieval Options
       -r
       --recursive
	   Turn on recursive retrieving.

       -l depth
       --level=depth
	   Specify recursion maximum depth level depth.  The default maximum depth is 5.

       --delete-after
	   This option tells Wget to delete every single file it downloads, after having done so.
	   It is useful for pre-fetching popular pages through a proxy, e.g.:

		   wget -r -nd --delete-after http://whatever.com/~popular/page/

	   The -r option is to retrieve recursively, and -nd to not create directories.

	   Note that --delete-after deletes files on the local machine.  It does not issue the
	   DELE command to remote FTP sites, for instance.  Also note that when --delete-after is
	   specified, --convert-links is ignored, so .orig files are simply not created in the
	   first place.

       -k
       --convert-links
	   After the download is complete, convert the links in the document to make them
	   suitable for local viewing.	This affects not only the visible hyperlinks, but any
	   part of the document that links to external content, such as embedded images, links to
	   style sheets, hyperlinks to non-HTML content, etc.

	   Each link will be changed in one of the two ways:

	   o   The links to files that have been downloaded by Wget will be changed to refer to
	       the file they point to as a relative link.

	       Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
	       downloaded, then the link in doc.html will be modified to point to ../bar/img.gif.
	       This kind of transformation works reliably for arbitrary combinations of
	       directories.

	   o   The links to files that have not been downloaded by Wget will be changed to
	       include host name and absolute path of the location they point to.

	       Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
	       ../bar/img.gif), then the link in doc.html will be modified to point to
	       http://hostname/bar/img.gif.

	   Because of this, local browsing works reliably: if a linked file was downloaded, the
	   link will refer to its local name; if it was not downloaded, the link will refer to
	   its full Internet address rather than presenting a broken link.  The fact that the
	   former links are converted to relative links ensures that you can move the downloaded
	   hierarchy to another directory.

	   Note that only at the end of the download can Wget know which links have been
	   downloaded.	Because of that, the work done by -k will be performed at the end of all
	   the downloads.

       -K
       --backup-converted
	   When converting a file, back up the original version with a .orig suffix.  Affects the
	   behavior of -N.

       -m
       --mirror
	   Turn on options suitable for mirroring.  This option turns on recursion and time-
	   stamping, sets infinite recursion depth and keeps FTP directory listings.  It is
	   currently equivalent to -r -N -l inf --no-remove-listing.

       -p
       --page-requisites
	   This option causes Wget to download all the files that are necessary to properly
	   display a given HTML page.  This includes such things as inlined images, sounds, and
	   referenced stylesheets.

	   Ordinarily, when downloading a single HTML page, any requisite documents that may be
	   needed to display it properly are not downloaded.  Using -r together with -l can help,
	   but since Wget does not ordinarily distinguish between external and inlined documents,
	   one is generally left with "leaf documents" that are missing their requisites.

	   For instance, say document 1.html contains an "<IMG>" tag referencing 1.gif and an
	   "<A>" tag pointing to external document 2.html.  Say that 2.html is similar but that
	   its image is 2.gif and it links to 3.html.  Say this continues up to some arbitrarily
	   high number.

	   If one executes the command:

		   wget -r -l 2 http://<site>/1.html

	   then 1.html, 1.gif, 2.html, 2.gif, and 3.html will be downloaded.  As you can see,
	   3.html is without its requisite 3.gif because Wget is simply counting the number of
	   hops (up to 2) away from 1.html in order to determine where to stop the recursion.
	   However, with this command:

		   wget -r -l 2 -p http://<site>/1.html

	   all the above files and 3.html's requisite 3.gif will be downloaded.  Similarly,

		   wget -r -l 1 -p http://<site>/1.html

	   will cause 1.html, 1.gif, 2.html, and 2.gif to be downloaded.  One might think that:

		   wget -r -l 0 -p http://<site>/1.html

	   would download just 1.html and 1.gif, but unfortunately this is not the case, because
	   -l 0 is equivalent to -l inf---that is, infinite recursion.	To download a single HTML
	   page (or a handful of them, all specified on the command-line or in a -i URL input
	   file) and its (or their) requisites, simply leave off -r and -l:

		   wget -p http://<site>/1.html

	   Note that Wget will behave as if -r had been specified, but only that single page and
	   its requisites will be downloaded.  Links from that page to external documents will
	   not be followed.  Actually, to download a single page and all its requisites (even if
	   they exist on separate websites), and make sure the lot displays properly locally,
	   this author likes to use a few options in addition to -p:

		   wget -E -H -k -K -p http://<site>/<document>

	   To finish off this topic, it's worth knowing that Wget's idea of an external document
	   link is any URL specified in an "<A>" tag, an "<AREA>" tag, or a "<LINK>" tag other
	   than "<LINK REL="stylesheet">".

       --strict-comments
	   Turn on strict parsing of HTML comments.  The default is to terminate comments at the
	   first occurrence of -->.

	   According to specifications, HTML comments are expressed as SGML declarations.
	   Declaration is special markup that begins with <! and ends with >, such as <!DOCTYPE
	   ...>, that may contain comments between a pair of -- delimiters.  HTML comments are
	   "empty declarations", SGML declarations without any non-comment text.  Therefore,
	   <!--foo--> is a valid comment, and so is <!--one-- --two-->, but <!--1--2--> is not.

	   On the other hand, most HTML writers don't perceive comments as anything other than
	   text delimited with <!-- and -->, which is not quite the same.  For example, something
	   like <!------------> works as a valid comment as long as the number of dashes is a
	   multiple of four (!).  If not, the comment technically lasts until the next --, which
	   may be at the other end of the document.  Because of this, many popular browsers
	   completely ignore the specification and implement what users have come to expect:
	   comments delimited with <!-- and -->.

	   Until version 1.9, Wget interpreted comments strictly, which resulted in missing links
	   in many web pages that displayed fine in browsers, but had the misfortune of
	   containing non-compliant comments.  Beginning with version 1.9, Wget has joined the
	   ranks of clients that implements "naive" comments, terminating each comment at the
	   first occurrence of -->.

	   If, for whatever reason, you want strict comment parsing, use this option to turn it
	   on.

   Recursive Accept/Reject Options
       -A acclist --accept acclist
       -R rejlist --reject rejlist
	   Specify comma-separated lists of file name suffixes or patterns to accept or reject.
	   Note that if any of the wildcard characters, *, ?, [ or ], appear in an element of
	   acclist or rejlist, it will be treated as a pattern, rather than a suffix.

       -D domain-list
       --domains=domain-list
	   Set domains to be followed.	domain-list is a comma-separated list of domains.  Note
	   that it does not turn on -H.

       --exclude-domains domain-list
	   Specify the domains that are not to be followed..

       --follow-ftp
	   Follow FTP links from HTML documents.  Without this option, Wget will ignore all the
	   FTP links.

       --follow-tags=list
	   Wget has an internal table of HTML tag / attribute pairs that it considers when
	   looking for linked documents during a recursive retrieval.  If a user wants only a
	   subset of those tags to be considered, however, he or she should be specify such tags
	   in a comma-separated list with this option.

       --ignore-tags=list
	   This is the opposite of the --follow-tags option.  To skip certain HTML tags when
	   recursively looking for documents to download, specify them in a comma-separated list.

	   In the past, this option was the best bet for downloading a single page and its
	   requisites, using a command-line like:

		   wget --ignore-tags=a,area -H -k -K -r http://<site>/<document>

	   However, the author of this option came across a page with tags like "<LINK REL="home"
	   HREF="/">" and came to the realization that specifying tags to ignore was not enough.
	   One can't just tell Wget to ignore "<LINK>", because then stylesheets will not be
	   downloaded.	Now the best bet for downloading a single page and its requisites is the
	   dedicated --page-requisites option.

       --ignore-case
	   Ignore case when matching files and directories.  This influences the behavior of -R,
	   -A, -I, and -X options, as well as globbing implemented when downloading from FTP
	   sites.  For example, with this option, -A *.txt will match file1.txt, but also
	   file2.TXT, file3.TxT, and so on.

       -H
       --span-hosts
	   Enable spanning across hosts when doing recursive retrieving.

       -L
       --relative
	   Follow relative links only.	Useful for retrieving a specific home page without any
	   distractions, not even those from the same hosts.

       -I list
       --include-directories=list
	   Specify a comma-separated list of directories you wish to follow when downloading.
	   Elements of list may contain wildcards.

       -X list
       --exclude-directories=list
	   Specify a comma-separated list of directories you wish to exclude from download.
	   Elements of list may contain wildcards.

       -np
       --no-parent
	   Do not ever ascend to the parent directory when retrieving recursively.  This is a
	   useful option, since it guarantees that only the files below a certain hierarchy will
	   be downloaded.

EXIT STATUS
       Wget may return one of several error codes if it encounters problems.

       0   No problems occurred.

       1   Generic error code.

       2   Parse error---for instance, when parsing command-line options, the .wgetrc or
	   .netrc...

       3   File I/O error.

       4   Network failure.

       5   SSL verification failure.

       6   Username/password authentication failure.

       7   Protocol errors.

       8   Server issued an error response.

       With the exceptions of 0 and 1, the lower-numbered exit codes take precedence over higher-
       numbered ones, when multiple types of errors are encountered.

       In versions of Wget prior to 1.12, Wget's exit status tended to be unhelpful and
       inconsistent. Recursive downloads would virtually always return 0 (success), regardless of
       any issues encountered, and non-recursive fetches only returned the status corresponding
       to the most recently-attempted download.

FILES
       /etc/wgetrc
	   Default location of the global startup file.

       .wgetrc
	   User startup file.

BUGS
       You are welcome to submit bug reports via the GNU Wget bug tracker (see
       <http://wget.addictivecode.org/BugTracker>).

       Before actually submitting a bug report, please try to follow a few simple guidelines.

       1.  Please try to ascertain that the behavior you see really is a bug.  If Wget crashes,
	   it's a bug.	If Wget does not behave as documented, it's a bug.  If things work
	   strange, but you are not sure about the way they are supposed to work, it might well
	   be a bug, but you might want to double-check the documentation and the mailing lists.

       2.  Try to repeat the bug in as simple circumstances as possible.  E.g. if Wget crashes
	   while downloading wget -rl0 -kKE -t5 --no-proxy http://yoyodyne.com -o /tmp/log, you
	   should try to see if the crash is repeatable, and if will occur with a simpler set of
	   options.  You might even try to start the download at the page where the crash
	   occurred to see if that page somehow triggered the crash.

	   Also, while I will probably be interested to know the contents of your .wgetrc file,
	   just dumping it into the debug message is probably a bad idea.  Instead, you should
	   first try to see if the bug repeats with .wgetrc moved out of the way.  Only if it
	   turns out that .wgetrc settings affect the bug, mail me the relevant parts of the
	   file.

       3.  Please start Wget with -d option and send us the resulting output (or relevant parts
	   thereof).  If Wget was compiled without debug support, recompile it---it is much
	   easier to trace bugs with debug support on.

	   Note: please make sure to remove any potentially sensitive information from the debug
	   log before sending it to the bug address.  The "-d" won't go out of its way to collect
	   sensitive information, but the log will contain a fairly complete transcript of Wget's
	   communication with the server, which may include passwords and pieces of downloaded
	   data.  Since the bug address is publically archived, you may assume that all bug
	   reports are visible to the public.

       4.  If Wget has crashed, try to run it in a debugger, e.g. "gdb `which wget` core" and
	   type "where" to get the backtrace.  This may not work if the system administrator has
	   disabled core files, but it is safe to try.

SEE ALSO
       This is not the complete manual for GNU Wget.  For more complete information, including
       more detailed explanations of some of the options, and a number of commands available for
       use with .wgetrc files and the -e option, see the GNU Info entry for wget.
