.gitignore regex for emacs temporary files

Question

I\'m trying to .gitignore emacs temporary/autosave files. I\'m using...

\\.\\#.*

in my .gitignore.

But git add -A run in

Answer 1

gitignore doesn't use regular expressions. Instead it uses shell glob patters. The man page tells you two things important for this situation:

Otherwise, Git treats the pattern as a shell glob suitable for
consumption by fnmatch(3) with the FNM_PATHNAME flag.

and

A line starting with # serves as a comment. Put a backslash ("\")
in front of the first hash for patterns that begin with a hash.

This means that the pattern you want to use is simply .#*.

Now the second pattern that matov mentioned, #*, doesn't do anything as it is treated as a comment by git. Hence me quoting that second sentence from the man page.
