Create a global git commit hook

hooks.bash

1> Create a directory to hold the global hooks:
mkdir -p ~/git-templates/hooks


2> Enable git templates:
git config --global init.templatedir '~/git-templates'


3> Write your hooks in ~/.git-templates/hooks.
cd ~/git-templates/hooks && touch commit-msg

4> Copy Code to commit-msg file
```
#!/usr/bin/env bash

# regex to validate in commit msg
commit_regex='(build|doc|feat|fix|font|image|perf|refactor|style|test)\([a-z\-]+\)\:\s'
error_msg="Aborting commit. The commit message should be of the format '{type}({scope}): Your commit message'\n"
visit_link="Learn more @ https://github.com/WordImpress/Give/wiki/Prefixes\n"

if ! grep -iqE "$commit_regex" "$1"; then
    printf "\033[0;31m$error_msg $visit_link\033[0m" >&2
    exit 1
fi
```


5> Make sure the hook is executable.
chmod a+x ~/git-templates/hooks/commit-msg

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

Reset Git templates global

git config --global --unset-all init.templatedir

This can be implemented in one of the two ways. Git 2.9+ has a new setting called core.hooksPath which can be set to a custom folder that has the hooks. Another is to create symlinks. I opted for the 2nd approach assuming developers might not be on Git version 2.9+
