How to download a single commit-diff from GitHub?

Question

I would like to get a single commit (let's call it ${SHA}) from GitHub via the web-interface.

For example, something like:

$ git clone http://github.com/foo/bar
$ cd bar
$ git format-patch -o .. ${SHA}~1..${SHA}
$ cd ..
$ rm -rf bar

...but without having to clone the entire repository (the repo in question is large).

Obviously GitHub can display the diff of a given commit via the web interface, but how I can extract that into a (unified) diff-file (ideally, with the commit-message intact)?

Answer 1

OK, found the answer myself.

Adding .patch (or .diff) to the commit-URL will give a nice patch:

https://github.com/foo/bar/commit/${SHA}.patch
