An exception are hooks triggered during a push ('pre-receive', 'update', 'post-receive', 'post-update', 'push-to-checkout') which are always executed in $GIT_DIR. +Environment variables, such as `GIT_DIR`, `GIT_WORK_TREE`, etc., are exported +so that Git commands run by the hook can correctly locate the repository. If +your hook needs to invoke Git commands in a foreign repository or in a +different working tree of the same repository, then it should clear these +environment variables so they do not interfere with Git operations at the +foreign location. For example: + +------------ +local_desc=$(git describe) +foreign_desc=$(unset $(git rev-parse --local-env-vars); git -C ../foreign-repo describe) +------------ + Hooks can get their arguments via the environment, command-line arguments, and stdin. See the documentation for each hook below for details. |
