find and regular expressions
 

Hi all,

I could be me, but i don't seem to be able to make find working with regular expressions :-(

I've tried the parameter -regex followed by a countless number of attempts to get something out of it with no luck.

What I'm trying to find is:

1) directory names that have no space or multiple spaces before the character "["

2) directory names where tha value between square brackets is higher than 2012 e.g. "[2200]"

When I test my regular expressions against a regular-expression verification software it does the job, but when i use the very same strings with find... no luck!

e.g.

mywonderfuldirectory [2459]

find . -type d -regex ".*\[[0-9]{4}\]"

nothing is found

Can anybody please provide a working example?


Many thanks!!!

I think I've found the solution, find really needs the parameter:
-regextype posix-extended

now it works :-)

You may already know this, but many utilities require some kind of option setting when using extended regexes---eg
grep -e (or egrep)
sed -r

Fixed that for you.

Thank you!!!
