How to git grep in the whole tree when I'm in a subdirectory?
git, grep
Solution
Git aliases that run shell commands are always executed in the top level directory (see the `git config` man page), so you can add this to your `.gitconfig` file:
[alias]
rgrep = !git grep
Alternatively, you could use `git rev-parse --show-toplevel` to get the root directory, which you could then pass to `git grep` as the basis of a script or alias:
git grep $pattern -- `git rev-parse --show-toplevel`
Problem
Normally when I issue `git grep`, it will only search the current directory and below, for instance ``` $ cat A 1 $ cd d $ cat B 1 $ git grep 1 B:1 $ cd ..;git grep 1 A:1 B:1 ``` How can I tell `git grep` "search the entire tree, no matter the current working directory I'm in"?
