in thread compare most recent file with second most recent file and output difference

Hi, jjoseph8008

I'm not sure what's causing the problem within File::Slurp, so please try the following which doesn't use that Module:

use strict; use warnings; my ( %file1Hash, %file2Hash, %mergedHash ); my @files = sort { -M $a <=> -M $b } <"*.txt">; do { chomp; $file1Hash{$_}++ } for getFileLines($files[0]); $mergedHash{$_}++ for keys %file1Hash; do { chomp; $file2Hash{$_}++ } for getFileLines($files[1]); $mergedHash{$_}++ for keys %file2Hash; print "$_\n" for grep $mergedHash{$_} == 1, keys %mergedHash; sub getFileLines { open my $fh, '<', $_[0] or die $!; return <$fh>; }
