Re^2: regex question

you also don't escape characters in a character class.

That's not very good advice. Sometimes you certainly do need to escape characters in a character class. Take the following for example:

$ perl -le '$_ = q/f!o@o#b$a%r^b&a*z/; s/[!@#$%^&*]//g; print'

Or, even more drastical, see the difference in these lines: `perl -e '$_="bjzu-sbtz -abnzo-tbhze-rb zp-ebrzl- bhza-cbkze-r\n";s/[b-z]//g;print'` vs. `perl -e '$_="bjzu-sbtz -abnzo-tbhze-rb zp-ebrzl- bhza-cbkze-r\n";s/[b\-z]//g;print'` `s$$([},&%#}/&/]+}%&{});#$&&s&&$^X.($'^"%]=\&(\|?{%` `+`.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e	[reply] [d/l] [select]
