Re: Regex question

If the second variable is always just 2 numbers seperated by a "." I'd suggest doing it this way:

if ( "$var2." eq substr("$var1.", 0, 1+length $var2) ) { ... }

Not a regex thou...

Update at -2: Yes! It's not a regex. But: Why should one use a regex here where a simple string comparison will do?

Could those downvoters please comment what they think is wrong with my solution except that I don't break a fly on the wheel.

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

Very clever, adding a dot after the variables to make sure you do not get a false positive in case of partial matches! ++ wel deserved. CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply]
