Mirror To Non Bare Remote Repo

One thing to keep in mind is stash repositories are bare bone repositories, if you have a non-bare bone remote repository you will get an error like this:

$ git push --prune file:///Users/adriangonzalez/git/stash/test/rep_1 +refs/heads/*:refs/heads/* +refs/tags/*:refs/tags/*

If you need to have a non-bare remote repository, it is possible with the following steps on the remote machine:

1. Set receive.denyCurrentBranch = ignore:

$ git init
$ git config receive.denyCurrentBranch ignore

2. Create a post-receive hook:

$ touch .git/hooks/post-receive
$ chmod +x .git/hooks/post-receive
$ nano .git/hooks/post-receive

3. Use the following for your post-receive hook:

#!/bin/bash

test "${PWD%/.git}" != "$PWD" && cd .. 
unset GIT_DIR GIT_WORK_TREE

git reset --hard
