formatting text prior to using it it to post to cgi...

stevenrh has asked for the wisdom of the Perl Monks concerning the following question:

Hello All,

I have a script that posts to a cgi, using a file i downloaded and awk'd as input. I currently would like to eliminate the wak step, and use oerl instead.
the file comes with three(3)fields:

IP:aa:hex_value
so I have this command:
grep ^192.168. file | awk F: '(print $1)' | sort > newfile

then run my LWP/POST script

the following code was an attempt to get that fist column, and use it as my input.....all with perl, not the shell.


#!/usr/bin/perl -w
$|++;


use HTTP::Request::Common;
use LWP::UserAgent;

$ua = LWP::UserAgent->new;

my $file = 'fulldata';
open(FILE,"fulldata") || die "Could not open $file: $!";
while (<FILE>) {
        ($ip) = (split /:/) [0];
                if (/^192.168./) {
                chomp;

                $ua->request (POST 'http://domain.org/subgmit.cgi',
                        [ip    => "$_",
                        email => 'the_dude@dommain.net'
                                        ]);
}
last
}
close(INFO) or die "Error writing $file: $!";

Don't hold back, any (even brutal)advice is welcome...:() Thanks -stevenrh-

Your indenting "needs work". Don't you mean `open(FILE, $file)` instead of `open(FILE,"fulldata")`? Why don't you move the `chomp` right below the `while (<FILE>)`? Actually, you don't need the `chomp` at all since you discard the end of the line. Your `if` should be checking `$ip`, but it's checking `$_`. `/^192.168./` matches `'19231681'`. You want `/^192\.168\./`. You don't need the `split`. `($ip) = (split /:/)[0]; if ($ip =~ /^192.168./) {` can be replaced with `if (/^(192\.168\.\d{1,3}\.\d{1,3}):/) { $ip = $1;`. You're closing `INFO`, yet your handle is `FILE`. You don't check the results of `request` Your original code sorted the results, but your Perl script doesn't.	[reply] [d/l] [select]

I would like to eliminate the awk step, and use perl instead. Why? I mean, if it's just for learning purposes, fine. But you have a solution that ain't broke...	[reply]
