You can conveniently store the counts of particular "words" using a hash: `#!/usr/bin/env perl use strict; use warnings; my %freqs = (); # .... # for each match of $word $freqs{$word}++; # ... # the list the counts: foreach my $word (keys(%freqs)) { print "$word: $freqs{$word}\n"; } 1;` [download]	[reply] [d/l]

#!/usr/bin/env perl
use strict;
use warnings;

my %freqs = ();
# ....
# for each match of $word
  $freqs{$word}++;
  # ...
# the list the counts:
foreach my $word (keys(%freqs)) {
  print "$word: $freqs{$word}\n";
}

1;
