( #3333=superdoc: print w/ replies, xml ) Need Help??

Wasn't familiar with Syntax::Keyword::Junction, so I appreciate seeing it used here. Also, File::Slurp's a good module to use...

Since the OP's comparing lists, List::Compare can help find unique entries in file2.txt:

use Modern::Perl; use File::Slurp qw/read_file/; use List::Compare; my %hash; my @file1 = map { chomp; lc } read_file 'file1.txt'; my @file2 = map { chomp; lc } read_file 'file2.txt'; my $lc = List::Compare->new( \@file1, \@file2 ); my @file2Only = $lc->get_Ronly; say for @file2Only;

Output:

nt64osbld2 nt64osbld3 nt64oscitrix1 ntosbld4 ntosbld5 ntosbld6 vm-osw2k8x64-1 vm-osw2k8x64-2

Not in the OP's output formatting, but that wouldn't take much more...
