use strict; use warnings; while (<>) { my %sequences; for my $char ( split '', (split)[1] ) { $sequences{$char}++; } print "$_ => $sequences{$_}", "\n" for keys %sequences; }

Note how I declared the hash inside the loop. Scoping variables correctly is the easiest way to reset them.

[Corion]: marto: Oh, I'm jealous. I'm going to see DM in Frankfurt, but it's a stadium full of people, so, rather a big thing where you mostly get to see the band on screens ;)
[marto]: yes, the last time I saw them was in Berlin a few years ago, at the old Olympic stadium
[marto]: After Sunday I don't think I'll go see them again :)
[LanX]: Corion: come on, people are people! ;)
[Corion]: Naah, I think it's still an OK show so far. Their new songs aren't exactly great, but I'm not going there for new material anyway ;)
[marto]: I got the feeling from the last show that for big sections of it, they were not really into what they were doing
[Corion]: LanX: Sure, they can bask in my Halo
[marto]: more so than the previous show I saw
