Applying a git post-commit hook to all current and future repositories

As of Git 1.7.1, you can set init.templatedir in your gitconfig to tell Git where to look for templates.

Set it like this:

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

Afterward, new repositories you create or clone will use this directory for templates. Place the hooks you want in ~/.git_template/hooks. Existing repositories can be reinitialized with the proper templates by running git init in the same directory .git is in.

For Git versions older than 1.7.1, running git init --template ~/.git_template will work if you’re like me and still want to manage your .git_template directory along with the rest of your dot files. You can also use the $GIT_TEMPLATE_DIR environment to tell git init where your template directory is.
