Get number of files in git repository at any revision

Question

I'd like to be able to find the number of files in a Git repository at a given revision, preferably without having to check out the revision first.

I thought git ls-files might get me somewhere, but I'm not able to see any way of passing Git a revision for it.

Thanks in advance!

ls-files operates on the index, which is by nature associated with the current checkout. Use ls-tree , as in git ls-tree -r --name-only <tree-ish> . If you just want to count lines, using --name-only will speed things up by limiting the output.
