How to create a global git commit hook by Matt Venables

1 Enable git templates (This tells git to copy everything in ~/.git-templates to your per-project .git/ directory when you run git init):

git config --global init.templatedir '~/.git-templates'

2 Create a directory to hold the global hooks:

mkdir -p ~/.git-templates/hooks

3 Write your hooks in ~/.git-templates/hooks. For example, here's a post-merge hook (located in ~/.git-templates/hooks/post-merge):

vi ~/.git-templates/hooks/post-merge

#/usr/bin/env bash
# MIT © Sindre Sorhus - sindresorhus.com
# forked by Gianluca Guarini
# see https://gist.github.com/GianlucaGuarini/8001627

changed_files="$(git diff-tree -r --name-only --no-commit-id ORIG_HEAD HEAD)"

check_run() {
  echo "$changed_files" | grep -E --quiet "$1" && eval "$2"
}

# `composer install` if the `composer.lock` file gets changed
# Using a fully qualified path to composer to make this work in SourceTree
check_run composer.lock "/usr/local/bin/composer install"

4 Make sure the hook is executable.

chmod a+x ~/.git-templates/hooks/post-merge

5 Repeat steps 3 and 4 above, but create a ~/.git-templates/hooks/post-checkout file with the same contents so that this script is run whenever you checkout different branches.

6 Re-initialize git in each existing repo you'd like to use this in (NOTE if you already have a hook defined in your local git repo, this will not overwrite it):

git init

7 From now one, whenever you run git pull, git merge XXXXXXX, or git checkout in your project, if there are changes to the composer.lock file, the composer install command will be run.
