One way to count the occurrence of each character in a string:

#!/usr/bin/perl -w use strict; #never, never leave home without it my %chars = (); my $string = "J. J. is cool!"; foreach my $character (split //, $string) { $chars{$character}++; } print "Report:\n"; foreach my $key (keys %chars) { print "\t$key = $chars{$key}\n"; }
Yields:
[13:22:15 jhorner@gateway scripts]$ ./20000714-1.pl Report: = 3 ! = 1 o = 2 i = 1 J = 2 c = 1 s = 1 l = 1 . = 2

    [stevieb]: perldigious: video near our hq in Montreal. Here in Calgary, it's -28c... we've only got 3" of snow so far, but there are several feet in the mountains already
    [perldigious]: Snowshoeing time stevieb? I need to buy a pair so I can walk my German Shepherd properly through the country.
    [stevieb]: yeah, I snowshoe a fair amount in the mountains. I also use spikes similar to these very often as well
    [perldigious]: Discipulus: alternate link
    [stevieb]: LOL you can easily replace "Helsinki" with "Alberta"
    [perldigious]: I used to live at the top of a very steep hill stevieb, I can relate to the video. Literally used to have to build up momentum and try to force my vehicle to make it up the hill to park in my driveway properly... didn't always make it.
