Hi,
Alle Leerzeichen entfernen:
$string =~ s/\s//g; (
edit: drittes / nachgeholt)
Kleinbuchstaben:
$string = lc($string);
Umlaute musst Du ggf. gesondert berücksichtigen, je nach
locale.
edit: Kleinbuchstaben mittels RegEx:
$string =~ s/(.*)/\L$1/;

Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it? -- Brian Kernighan: "The Elements of Programming Style"
