How can I search all of my Git remote branches for the commit where a specific line or two of code were added (not just a file, but contents within them)?
My repos are all on github.

Please explain downvotes, this is an honest question that I am struggling with! – professormeowingtons Aug 17 '13 at 09:00

1What have you tied? You need to demonstrate that you have attempted to figure out the question on your own. – rudolph9 Aug 17 '13 at 13:41

Does git blame suit your needs? You can run it on a specific revision (irrelevant to whether it's on the remote or not, see How to 'git blame' on the remote-side repository?).
For example:
$ git blame master file_in_question.c
$ git blame 20f89e16 file_in_question.c
Also, if your repositories are on GitHub, you can use their interface to git blame if you'd prefer. See "Using git blame to trace changes in a file"

It might, but I need to check for specific contents of a file. How would I search through all commits, in all remote branches, looking for the point when a specific line of code was added? – professormeowingtons Aug 16 '13 at 19:08

1That's precisely what `git blame` does (see [Using git blame to trace changes in a file](https://help.github.com/articles/using-git-blame-to-trace-changes-in-a-file)). Just run `git blame
` for each non-merged branch (with merged branches, just take the more recent, `git blame` will navigate the whole history).

In addition to using git blame, you can also search in local branches with
git log -S<search-string> --source --all
It may search your local remote-tracking branches too, but I'm not sure. You could always just make a local branch of your remote ones, of course. See git: finding a commit that introduced a string for more details.
There's also a regex version that you could use (see git log docs):
-G<regex>Look for differences whose added or removed line matches the given
<regex>.
