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
