subsitute s/ and match m/ failure

kp2a has asked for the wisdom of the Perl Monks concerning the following question:

someone please point out error
#! /usr/bin/perl -w use strict; my $test = " v2.9.50"; my ($ip,$model) = split /:/,$test; $model =~ s/\.log$//; die if $model =~ /log/; print "<$ip> <$model>\n"; output [john@scan log]$ ./ <> <MikroTik v2.9.50> [john@scan log]$ perl -v This is perl, v5.8.8 built for i386-linux-thread-multi

I expected ".log" to be gone or die!

Update: sorry - obvious!

    since you split on ':' which is after .log,
    $ip =~ s/\.log$//;
    will do the trick.

    As clarification of what's been said elsewhere, you are testing the wrong element of the split ... to use your original code, change
    $model =~ s/\.log$//; die if $model =~ /log/;
    to read
    $ip =~ s/\.log$//; die if $ip =~ /log/;

    A user level that continues to overstate my experience :-))

    You're trying to strip '.log' of $model, where clearly you want to strip it of $ip.

    Hmm. What is obvious, i dont understand a word. Am I too silly? What is the failure? Or is there another context i might have missed?

    Thanks MH
      The OP replaced his original question with this meaningless reply to other replies. Hopefully the Janitors restore the original content.
