For starters, strictures and warnings.. Also, you are opening the files for writing, but using them for reading.

open my $fh1, "<", $file1 or die "Cannot open file $file1: $!"; open my $fh1, "<", $file2 or die "Cannot open file $file2: $!";

Then, with while ( <F1>, <F2> ), you'd be reading a line from each file, not assinging it to anything, and entering the loop; $_ is only set while using while (<$file>). (I think.)

Really, that's quite a bad post you have there. Still, I've never tried something like this, so have a freebie from another newbie (and please try to ignore the awful variable names..):

use strict; use warnings; use 5.010; use autodie; open my $fh1, '<', 'file1'; open my $fh2, '<', 'file2'; while (my $test1 = <$fh1>, my $test2 = <$fh2>) { chomp($test1 //= ''); chomp($test2 //= ''); say "$test1, $test2"; }
