in reply to Efficient code.

I'd do something like this (untested):
#!/usr/bin/perl -w use strict; my %firstfile; open IN_A, "<a.log" or die "$!\n"; while (<IN_A>) { chomp; $firstfile{$_}++; } close IN_A; open IN_B, "<b.log" or die "$!\n"; while (<IN_B>) { chomp; print if exists($firstfile{$_}); } close IN_B;

Cheers,
Darren :)
