Hi tachyon, thanks once again.

I wonder if you have time if you could help me unravel what you're doing!
If I'm correct you are saying $var minus $ILLEGAL_CHARS equals acceptable $var. However I don't understand the expression   $var = ";rm -rf /*;";   also   qr/[^A-Za-z0-9._-]/;   Am I right in thinking that   qr//;  allows you to assign the regex to the variable, rather than have it act upon the variable?

Also it looks as though the $ILLEGAL_CHARS are the one's that I would wish to keep (as per the sense of your explanation) but they are being removed from the variable.

I'm sorry if this all seems to be silly or uninformed - I am doing my best to make sense of it and I hope that by not flinching in asking silly questions now I might learn enough to start asking sensible questions in the first place!!
