Grep folder within thousands of folders

Question

I have a folder filled with approximately 5000 folders. I want to search within all these folders for folders beginning with numbers ie 089781 or 03828 for example.

What kind of regular expression could i use to do this?

Also im on windows and was planning to use the 'grepWin' program.

Help much appreciated

Answer 1

Easy on Unix / Cygwin;

find . -type d -name '[0-9]*'

You can probably find find ported to your platform.

That's just a glob, not a regex, btw.
