Find the SHA1 of the latest commit in a git branch

Here's a way to get the SHA1 of the last commit in a given branch in a way that can be used in a script easily. For humans `git log branchname` is probably fine - just read the first line. For a shell script that wants to get that value into a variable, here's a quick way to do that:

Seems like there ought to be an easier way...but not that I could find in less time than it took to write this command.

Markus - odd that didn't work for you. I heard the same from someone else commenting on the gist at

I've been using it in a script that runs on Linux and OS X for months and just tried it again and it works fine...

However, I think your way wins. That looks like the way it was meant to be done.

rev-parse offers yet another, even simpler way:

git rev-parse $branch

This is the simplest use of rev-parse.
