At the least, I recommending moving past `find . --name '*.foo' -exec grep` pattern if you can help it.

Modern file searchers, of which `ag` is one among others, accepts `--filenametype` argument and skips the `.git` subdirectory if it exists (by default, can be toggled), so `ag --python needle` will recursively search for needle in the the current working tree in all files whos filenames end in `.py`.

Yes, you could write a function to do the same in `find`, but then you're just being stubborn. (Which is fine; my .bashrc is littered with aliases and functions of me being stubborn, but if I have to copy my .bashrc file around, I might as well install my preferred searcher to the target system if available.)
