Script to allow multi hooks per hook type for git

git-multi-hook-template

#!/usr/bin/env bash

# Allow multiple hooks.
#
# To use it copy this script with executable permission in ".git/hooks/hook-name"
# where hook-name is the name of the hook (see man githooks to know available hooks).
# Then place your scripts with executable permission in ".git/hooks/hook-name.d/".

hook_type=${BASH_SOURCE##*/}

case "$hook_type" in
    applypatch-msg \
        |commit-msg \
        |fsmonitor-watchman \
        |post-checkout \
        |post-commit \
        |post-merge \
        |post-update \
        |pre-applypatch \
        |pre-commit \
        |prepare-commit-msg \
        |pre-push \
        |pre-rebase \
        |pre-receive \
        |update)
        IFS= read -rd '' stdin
        for file in "${BASH_SOURCE[0]}.d"/*; do
            "./$file" "$@" <<<"$stdin" || exit 2
        done
        exit 0
        ;;
    *)
        echo "unknown hook type: $hook_type"
        exit 2
        ;;
esac

By using "$file" instead of "./$file", running $file in line 28 works also when the $file path is absolute.

great idea, I changed it to return the exit status of the sub-command with "$file" || exit $?.

And removed the hook_type check, as I expect that the user is smart enough to search and realize that he's using an hook which does not exist. So the finale script is:

#!/usr/bin/env bash

# Allow multiple hooks.
#
# To use it copy this script in "~/.githooks" with the executable bit set. Then and set
# core.hooksPath to ~/.githooks: 'git config --global core.hooksPath ~/.githooks'.
# The name of the file, here described with the 'hook-name' placeholder, should be
# the name of the wanted hook (see man githooks to know available hooks).
# Then place your scripts with executable bit set in ".git/hooks/hook-name.d/".

for file in "${BASH_SOURCE[0]}.d"/*; do
    echo "##### GITHOOK: ${file}"
    "$file" || exit $?
done

Thank you all for the idea.

Hello, for your possible interest, here's an adaption that also takes care of the global hooks (introduced in 2.9): https://gist.github.com/Konfekt/d9e86763b0f3febd7b2f7ca589f6c482
