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;

[marioroy]: LA my @music_times = qx(find \$HOME/Music/ Albums -type f -iname \'*.mp3\' -exec mp3info -p \"%S\\n\" {} \\;);
[marioroy]: Only 2 backslash \\n
[marioroy]: LA no space before Albums
[Lady_Aleena]: Good guh! I think I will use File::Find when working in perl. That is too many toothpicks.
[marioroy]: mp3info must be in the PATH
[marioroy]: LA ++
[Lady_Aleena]: marioroy, this is forcing me to learn perl modules to use instead.
[marioroy]: qx isn't fun if having to backslash ' and " and \.
[marioroy]: LA ++ ok.
