Re: Comparing two files

[Tuna]

Use our very own davorg's Array::Compare

#!/usr/bin/perl -w

use strict;
use Array::Compare;

my $comp = Array::Compare->new(Sep => '|', WhiteSpace => 0, Case => 0)
+;

my $file1 = "/etc/modules.conf";
my $file2 = "/etc/modules.conf2";

open  FILE1, $file1 || die "Can't open file 1:$!\n"; my @lines1=<FILE1
+>;
open  FILE2, $file2 || die "Can't open file 2:$!\n"; my @lines2=<FILE2
+>;

if ($comp->compare(\@lines1, \@lines2)) {
  print "Arrays are the same\n";
} else {
  print "Arrays are different\n";
}

Thanks for the plug :)

Worth pointing out a couple of things:

1. This depends on reading your files into memory. If your files are large, this might not be such a good idea.
2. You should only change the 'Sep' character to something that won't appear in your data. In general the default value (^G) is fine.
