Well, that's exactly what tr does. Example: `perl -le '$line1 = "asdadAADSAsdfsfASASDjljsdASDAS"; $line1 =~ tr/[A-Z +a-z]/[a-zA-Z]/;print $line1;'` [download] Prints: `ASDADaadsaSDFSFasasdJLJSDasdas` [download]	[reply] [d/l] [select]

Transliteration doesn't use character classes. You don't need `[` and `]`, unless you actually intend to also transliterate those square bracket characters. What's needed is: `$line1 =~ tr/A-Za-z/a-zA-Z/` [download] ...assuming you're not dealing with some funky character set. Dave	[reply] [d/l] [select]

Ah, thanks for the correction. As I mentioned above, I've rarely used tr before, so it's not surprising that I got the example wrong :)	[reply]
