Gitignoring md5 files

Question

In one of my Git projects, I have files in md5 format that I want to ignore.

I tried to add the following entry to my .gitignore,

[0-9a-f]{32} 

but apparently .gitignore files do not support regexp. Is there an equivalent way to achieve that?

Answer 1

[0-9a-f]{32} does not work,

but

[0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f]

does (although it is very ugly).
