in reply to count multiple variables in a single array.

As an example of what 1nickt suggested, maybe something like:

c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -e "my @files = qw( TUMI-1354839054_alt1 1.psd maur-1111.psd Sam-I-Am.gif maur-1110.psd ); ;; my %user_tag_title = qw(TUMI TUMI BW BW maur maurices); ;; my ($rx_user_search) = map qr{ $_ }xms, join ' | ', map quotemeta, reverse sort keys %user_tag_title ; print $rx_user_search, qq{\n}; ;; my %files_seen; FILE: for my $file (@files) { next FILE unless my ($user) = $file =~ m{ ($rx_user_search) }xms; push @{ $files_seen{$user} }, $file; } dd \%files_seen ;; USER: for my $user (sort keys %user_tag_title) { next USER unless exists $files_seen{$user}; ;; printf qq{%d $user_tag_title{$user} files \n%s \n\n}, scalar(@{ $files_seen{$user} }), join qq{\n}, @{ $files_seen{$user} }; } " (?msx-i: maur | TUMI | BW ) { TUMI => ["TUMI-1354839054_alt1"], maur => ["maur-1111.psd", "maur-1110.psd"], } 1 TUMI files TUMI-1354839054_alt1 2 maurices files maur-1111.psd maur-1110.psd
