Re^2: How do you make a regex non greedy

Not so simple. You have also to anchor the left hand end:

s/^.*?TEST/TEST/

Update: Argh - one day I'll stop getting bitten by that! Anonymous Monk is quite right. No backtracking is required to get a match so .*? matches everything from the start or the string up to TEST - no anchor needed.

True laziness is hard work

Yes, it is precisely that simple `$_ = '1 TEST 2 TEST 3 TEST'; s/.*?TEST/TEST/; print; __END__ TEST 2 TEST 3 TEST` [download]	[reply] [d/l]
