Can I git grep across all revisions in a Git repository? How?
I need to search for a sequence of digits. I'm interested in the contents of files, not just commit messages or hashes. It is acceptable to limit the search to only .java files, if it helps.
This doesn't work. The repository is big, it may have something to do with it.
git grep "509038" $(git rev-list --all)

You can use git log --all -S<some-text> to find commits where that piece of text is added/removed in history. @LeGEC provided a tip to use -G<some-text> which, after reading how it differs from -S, sounds handy too.

-S<string>
Look for differences that change the number of occurrences of the specified <string> (i.e. addition/deletion) in a file. Intended for the scripter’s use.
It is useful when you’re looking for an exact block of code (like a struct), and want to know the history of that block since it first came into being: use the feature iteratively to feed the interesting block in the preimage back into -S, and keep going until you get the very first version of the block.
Binary files are searched as well.
-G<regex>
Look for differences whose patch text contains added/removed lines that match <regex>.
To illustrate the difference between -S<regex> --pickaxe-regex and -G<regex>, consider a commit with the following diff in the same file:
+ return frotz(nitfol, two->ptr, 1, 0);
...
- hit = frotz(nitfol, mf2.ptr, 1, 0);
While git log -G"frotz\(nitfol" will show this commit, git log -S"frotz\(nitfol" --pickaxe-regex will not (because the number of occurrences of that string did not change).
Unless --text is supplied patches of binary files without a textconv filter will be ignored.
See the pickaxe entry in gitdiffcore[7] for more information.
