in reply to Comparing two hashes

As other monks have pointed out, the question is a little vague. If what you're trying to do is compare elements in one hash with elements in another hash, and the key values do not matter, you could use code something like this:

#!/usr/bin/perl use warnings; use strict; my %giant = ( fee => 'fi', fo => 'fum', I => 'smell' ); my %mouse = ( eeeny => 'meeny', miny => 'mo', nose => 'smell' ); my $out = "giant\{%s\} equals mouse\{%s\}\n"; for my $g ( sort keys %giant ) { for my $m ( sort keys %mouse ) { printf $out, $g, $m if ( $giant{$g} eq $mouse{$m} ); } }

      Actually, that's what I intended to do, ruzam. And that's what I said I was going to do. One example, of one possible interpretation of the OP's question, was all I wanted to provide.
        My bad, sorry. You're absolutely right and I should have read your response more carefully. I'm afraid I got caught up in the code example without paying attention to the lead in.
