Variables in perl script
Hi Chaps,
Im after some advise with a script i've written however doesnt appear to work how I would like.

Basically I have a perl script which sucessfully pulls an expect script to login to multiple nodes and obtain some output from the nodes (total number of nat ports that are in use for the relivant pool on that node).

What I want to archieve is a list of the pools from each node with the number of ports in use, They if a single nat pool is using less than x number of ports to email me.

Firstly my perl script doesn't seem to output the details as I would like, for each pool i want the line to show the node name, then the port details (as per the below, what you will notice is in the output below the node name appears to be on the line above the port details) possibly due to control characters but not sure how is best to deal with this ?

Script:
Code:
#!/usr/bin/perl -w
use Term::ANSIColor;
use strict;
use constant DEBUG => 1;
my $pool0 = "";
my $pool1 = "";
my $filename = "list.txt";
open(my $fh, "<", $filename) or die "couldn't read file";
while (my $line = <$fh>){
        for (`../user/test2.sh $line`) {
                                if (/pool0\s\S+\s+\S+\s+\S+\s+(\S+)/) {
                                        $pool0 = $1;
                                print color("red"), "$line pool0 ports in use $pool0\n", color("reset");
                                }
                                if (/pool1\s\S+\s+\S+\s+\S+\s+(\S+)/) {
                                        $pool1 = $1;
                                print color("red"), "$line pool1 ports in use $pool1\n", color("reset");
                                }

                        }
}
exit 0;

Output with new lines between node name and value although I want it all in one line.

Code:
RN001
 pool0 ports in use 415963
RN001
 pool1 ports in use 425610
RB001
 pool1 ports in use 323477
RB001
 pool0 ports in use 325010

Also could anyone help in regards to how i can I check multiple nat pool values that the script puts into variables (pool0, pool1 etc) to send an email to me if any of them fall below a certain number of ports in us.

I want an email on a per node basis rather than per pool, It should only generate an email if it falls below the configured value.

Thanks for the help

test::script

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME

       Test::Script - Basic cross-platform tests for scripts

DESCRIPTION

       The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or
       bin as is also commonly used) paths of your Perl distribution.

       Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible.

       That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is
       considered unacceptable.

       In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking
       that your module won't on some platform because of the dependency.

       Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform
       safety.

FUNCTIONS

   script_compiles
	   script_compiles( 'script/foo.pl', 'Main script compiles' );

       The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl).
       This will also be shown in the diagnostic output on failure.

   script_runs
	   script_runs( 'script/foo.pl', 'Main script runs' );

       The "script_runs" test executes the script with "perl script.pl" and checks that it returns success.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also
       be shown in the diagnostic output on failure.
