Re: matching file names using regex

Another way:

/^(?!.*~$)test\d+/

A couple notes about a few of the previously presented regexes. In this node {1,} is functionally equivalent to just + as both mean 1 or more times. Not that it is wrong just equivalent (as the OP is a beginner).

In Re: matching file names using regex one of the tests (/^test\d+.*/) has a .* at the end which unless you are meaning to capture something with it really serves no purpose as .* means match as much of anything as you can (as much can be as little as 0, which is guaranteed to match, so it is unnecessary). Again not necessarily wrong. To be honest I would probably choose the two test solution as it is more clear at to what one is doing.

Your solution is good and it may even be efficient thanks to anchoring, but stylistically, I guess I just don't like `$` or `\z` anywhere but the end of the regex. That's just a matter of taste, as your other comments also illustrate. -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l] [select]
