It looks like you have to bind stderror with stdout to get the output into a variable. 2>&1
# URL port Variables
Use $var so they will get expanded by bash.
If you want an array for record keeping or logging or whatever, building the array in a loop might be better...

Hello guys.
In my script, i have the following code:
echo "The tarfile contains these directorys"
tar -tf file.tar > tarlist.txt
cat tarlist | awk -F/ '{print $1 "/" $2}' | nl
echo "Enter path of the directory you want to extract or just press enter to extract everything: "

I need to check if $1 or $2 are empty before continuing but I don't know if bash has any logic of the sort. This is what I'm looking for - except that "and" doesn't seem to work.
if and ;then

Thank you! :D (4 Replies)
hi all i am trying to save an awk value into an array in bash:

$count is to keep track of file numbers (1.txt,2.txt,3.txt,etc.)

Apologies for the utter triviality of this question, but we all have to start somewhere! I've also tried searching but this question is pretty vague so I didn't (a) really know what to search for or (b) get many relevant hits to what I did search for.

Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

Hi gurus,
I need to create arrays from variables, via a loop.
The issue I have is with the array name creation. How do I use a variable to define an array?

Apache2::URI - Perl API for manipulating URIs
Synopsis
use Apache2::URI ();
$hostport = $r->construct_server();
$hostport = $r->construct_server($hostname);
$hostport = $r->construct_server($hostname, $port);
$hostport = $r->construct_server($hostname, $port, $pool);
$url = $r->construct_url();
$url = $r->construct_url($rel_uri);
$url = $r->construct_url($rel_uri, $pool);
$parsed_uri = $r->parse_uri($uri);
$parsed_uri = $r->parsed_uri();
$url = join '%20', qw(one two three);
Apache2::URI::unescape_url($url);
Description
While "APR::URI" provides a generic API to dissect, adjust and put together any given URI string, "Apache2::URI" provides an API specific
to Apache, by taking the information directly from the $r object. Therefore when manipulating the URI of the current HTTP request usually
methods from both classes are used.
API
"Apache2::URI" provides the following functions and methods:
"construct_server"
Construct a string made of hostname and port
$hostport = $r->construct_server();
$hostport = $r->construct_server($hostname);
$hostport = $r->construct_server($hostname, $port);
$hostport = $r->construct_server($hostname, $port, $pool);
obj: $r ( "Apache2::RequestRec object" )
The current request object
opt arg1: $hostname ( string )
The hostname of the server.
If that argument is not passed, "$r->get_server_name" is used.
opt arg2: $port ( string )
The port the server is running on.
If that argument is not passed, "$r->get_server_port" is used.
opt arg3: $pool ( "APR::Pool object" )
The pool to allocate the string from.
If that argument is not passed, "$r->pool" is used.
ret: $hostport ( string )
The server's hostport string
since: 2.0.00
Examples:
o Assuming that:
$r->get_server_name == "localhost";
$r->get_server_port == 8001;
The code:
$hostport = $r->construct_server();
returns a string:
localhost:8001
o The following code sets the values explicitly:
$hostport = $r->construct_server("my.example.com", 8888);
and it returns a string:
my.example.com:8888
"construct_url"
Build a fully qualified URL from the uri and information in the request rec:
$url = $r->construct_url();
$url = $r->construct_url($rel_uri);
$url = $r->construct_url($rel_uri, $pool);
obj: $r ( "Apache2::RequestRec object" )
The current request object
opt arg1: $rel_uri ( string )
The path to the requested file (it may include a concatenation of path, query and fragment components).
If that argument is not passed, "$r->uri" is used.
opt arg2: $pool ( "APR::Pool object" )
The pool to allocate the URL from
If that argument is not passed, "$r->pool" is used.
ret: $url ( string )
A fully qualified URL
since: 2.0.00
Examples:
o Assuming that the request was
http://localhost.localdomain:8529/test?args
The code:
my $url = $r->construct_url;
returns the string:
http://localhost.localdomain:8529/test
notice that the query (args) component is not in the string. You need to append it manually if it's needed.
o Assuming that the request was
http://localhost.localdomain:8529/test?args
The code:
my $rel_uri = "/foo/bar?tar";
my $url = $r->construct_url($rel_uri);
returns the string:
http://localhost.localdomain:8529/foo/bar?tar
"parse_uri"
Break apart URI (affecting the current request's uri components)
$r->parse_uri($uri);
obj: $r ( "Apache2::RequestRec object" )
The current request object
arg1: $uri ( string )
The uri to break apart
ret: no return value
warning:
This method has several side-effects explained below
since: 2.0.00
This method call has the following side-effects:
1. sets "$r->args" to the rest after '?' if such exists in the passed $uri, otherwise sets it to "undef".
2. sets "$r->uri" to the passed $uri without the "$r->args" part.
3. sets "$r->hostname" (if not set already) using the ("scheme://host:port") parts of the passed $uri.
"parsed_uri"
Get the current request's parsed uri object
my $uri = $r->parsed_uri();
obj: $r ( "Apache2::RequestRec object" )
The current request object
ret: $uri ( "APR::URI object" )
The parsed uri
since: 2.0.00
This object is suitable for using with "APR::URI::rpath"
"unescape_url"
Unescape URLs
Apache2::URI::unescape_url($url);
obj: $url ( string )
The URL to unescape
ret: no return value
The argument $url is now unescaped
since: 2.0.00
Example:
my $url = join '%20', qw(one two three);
Apache2::URI::unescape_url($url);
$url now contains the string:
"one two three";
