help extended regex Sequence \w 2

[ability1]

I know \w will match any "word" character (alphanumerics plus "_&quot.

But what would match any "word" character EXCLUDING "_" (the underscore).

 

[raklet]

\w is a shortcut for the pattern class [_0-9a-zA-Z]. So just use the pattern class minus the "_".


$match =~ /[0-9a-zA-z]{3}/;

will match any three characters that are in the range given.
