In a git hook is the current working directory guaranteed to be within the git repository?

Question

Experimentally it seems that git hooks get run with the current directory set to be the root of the repository. However, I can\'t see any guarantee about that in the git doc

Answer 1

It is based on the value set for environment variable GIT_DIR. It is set to the root of the repository when the hook starts running. Many hooks, especially those doing a pull from another repo, unset ( and reset) this environment variable as needed.
