How to create a global git commit hook by [Matt Venables](https://coderwall.com/p/jp7d5q) 

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-commit hook (located in ~/.git-templates/hooks/post-commit):

```

#!/bin/sh

# Copy last commit hash to clipboard on commit
git log -1 --format=format:%h | pbcopy


# Add other post-commit hooks 

```

4 Make sure the hook is executable.

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

5 Re-initialize git in each existing repo you'd like to use this in:

``git init``

NOTE if you already have a hook defined in your local git repo, this will not overwrite it.
