NAME
       ncftpget - Internet file transfer program for scripts

SYNOPSIS
       ncftpget [options] remote-host local-directory remote-files...

       ncftpget -f login.cfg [options] local-directory remote-files...

       ncftpget [options] ftp://url.style.host/path/name

       ncftpget -c [options] remote-host remote-file > stdout

       ncftpget -c [options] ftp://url.style.host/path/name > stdout

OPTIONS
   Command line flags:
       -u XX   Use username XX instead of anonymous.

       -p XX   Use password XX with the username.

       -P XX   Use port number XX instead of the default FTP service port (21).

       -j XX   Use account XX in supplement to the username and password (deprecated).

       -d XX   Use the file XX for debug logging.

       -a      Use ASCII transfer type instead of binary.

       -t XX   Timeout after XX seconds.

       -v/-V   Do  (do	not)  use  progress meters.  The default is to use progress meters if the
	       output stream is a TTY.

       -f XX   Read the file XX for host, user, and password information.

       -c      Send output to standard out, rather than writing to a local file.

       -A      Append to local files, instead of overwriting them.

       -z/-Z   Do (do not) try to resume transfers.  The default is to try to resume (-z).

       -E      Use regular (PORT) data connections.

       -F      Use passive (PASV) data connections.  The default is to use passive, but to  fall-
	       back to regular if the passive connection fails or times out.

       -DD     Delete remote file after successfully downloading it.

       -R      Recursive mode; copy whole directory trees.

       -T      Do  not	use  automatic on-the-fly TAR mode for downloading whole directory trees.
	       ncftpget uses TAR whenever possible since this usually  preserves  symbolic  links
	       and  file  permissions.	TAR mode can also result in faster transfers for directo-
	       ries containing many small files, since a  single  data	connection  can  be  used
	       rather than an FTP data connection for each small file.	The downside to using TAR
	       is that it forces downloading of the whole directory, even if you  had  previously
	       downloaded a portion of it earlier, so you may want to use this option if you want
	       to resume downloading of a directory.

       -r XX   Redial a maximum of XX times until connected to the remote FTP server.

       -b      Run in background (by submitting a batch job and then spawning ncftpbatch).

       -bb     Similar to -b option, but only submits the batch job.  You will need to run ncftp-
	       batch  for  the	batch  job to be processed.  This is useful if you already have a
	       ncftpbatch process running, or wish to have better control of when batch jobs  are
	       processed.

	       For  example,  if you wanted to do background processing of three files all on the
	       same remote server, it is more polite  to  use  just  one  ncftpbatch  process  to
	       process the three jobs sequentially, rather than having three ncftpbatch processes
	       open three simultaneous FTP sessions to the same server.

       -B XX   Try setting the TCP/IP socket buffer size to XX bytes.

       -W XX   Send raw FTP command XX after logging in.

       -X XX   Send raw FTP command XX after each file transferred.

       -Y XX   Send raw FTP command XX before logging out.

	       The -W, -X, and -Y options are useful for advanced users who need to tweak  behav-
	       ior  on	some servers.  For example, users accessing mainframes might need to send
	       some special SITE commands to set blocksize and record format information.

	       For these options, you can use them multiple times each if you need to send multi-
	       ple  commands.	For  the  -X option, you can use the cookie %s to expand into the
	       name of the file that was transferred.

DESCRIPTION
       The purpose of ncftpget is to do file transfers from the command-line without entering  an
       interactive  shell.   This lets you write shell scripts or other unattended processes that
       can do FTP.  It is also useful for advanced users who want  to  retrieve  files	from  the
       shell command line without entering an interactive FTP program such as ncftp.

       One particularly useful feature of this program is that you can give it a uniform resource
       locator as the only argument and the program will download that file.  You can  then  copy
       and paste from your web browser or newsreader and use that URL.	Example:

	   $ cd /tmp
	   $ ncftpget ftp://ftp.ncftp.com/pub/ncftp/ncftp.tar.Z
	   $ zcat ncftp.tar.Z | tar xf -

       By  default  the  program tries to open the remote host and login anonymously, but you can
       specify a username and password information.  The -u option is used to specify  the  user-
       name  to  login as, and the -p option is used to specify the password.  If you are running
       the program from the shell, you may omit the -p option and the program will prompt you for
       the password.

       Using  the  -u  and  -p	options  are not recommended, because your account information is
       exposed to anyone who can see your shell script or your process information.  For example,
       someone using the ps program could see your password while the program runs.

       You  may  use  the -f option instead to specify a file with the account information.  How-
       ever, this is still not secure because anyone who has read access to the information  file
       can  see  the  account  information.  Nevertheless, if you choose to use the -f option the
       file should look something like this:

	   host sphygmomanometer.ncftp.com
	   user gleason
	   pass mypasswd

       Don't forget to change the permissions on this file so no one else can read them.

       The -d option is very useful when you are trying to diagnose why a file transfer is  fail-
       ing.  It prints out the entire FTP conversation to the file you specify, so you can get an
       idea of what went wrong.  If you specify the special name stdout as the name of the debug-
       ging output file, the output will instead print to the screen.  Example:

	   $ ncftpget -d stdout bowser.nintendo.co.jp . /pub/README
	   220: FTP server ready.
	   Connected to bowser.nintendo.co.jp.
	   Cmd: USER anonymous
	   331: Guest login ok, send your complete e-mail address as password.
	   Cmd: PASS xxxxxxxx
	   230: Welcome!
	   Logged in to bowser.nintendo.co.jp as anonymous.
	   Cmd: TYPE I
	   200: Type set to I.
	   Cmd: PORT 192,168,9,37,6,76
	   200: PORT command successful.
	   Cmd: RETR /pub/README
	   550: /pub/README: File in use.
	   Cmd: QUIT
	   221: Goodbye.

       Using  ASCII  mode  is  helpful when the text format of your host differs from that of the
       remote host.  For example, if you are retrieving a .TXT file from a Windows-based host  to
       a  UNIX	system, you could use the -a flag which would use ASCII transfer mode so that the
       file created on the UNIX system would be in the UNIX text format  instead  of  the  MS-DOS
       text format.

       You  can  retrieve  an entire directory tree of files by using the -R flag.  However, this
       will work only if the remote FTP server is a UNIX server, or emulates UNIX's list  output.
       Example:

	   $ ncftpget -R ftp.ncftp.com /tmp /pub/ncftp

       This would create a /tmp/ncftp hierarchy.
