in reply to Regular Expression Builder

Given a string like "Rich36!", it would produce \w{4}\d{2}\! or \w+\d+\!.

And why wouldn't it produce one of these

/\w{6}!/ /\w+!/ /[A-Z][a-z]{3}\d\d!/ /Rich36!/ /......./ /\S+/ /.*/

I mean, the tightest or least general thing it could produce when given a $string is just /\Q$string\E/ and the most general thing would be /.*/s, and between those is a rather large space of candidates.

[Lady_Aleena]: shmem, that is understandable! The two examples in File::Find don't make sense to me on a quick glance.
[marioroy]: LA if the find worked from Unix command line, or does it not. Likely a quoting issue inside Perl qx.
[Lady_Aleena]: marioroy, the find worked fine at the command line.
[marioroy]: LA, yeah. than there's no reason why it cannot work inside qx. But chatting is hard in PM. I cannot see the code now.
[shmem]: Lady_Aleena: sometimes a quick glance isn't enough.
