jdpaton / git-split-subfolder.sh

Created August 27, 2013 20:49

This script splits a subfolder of an existing git repo into its own separate repo. It will preserve all tags by default, and any branches specified with '-b'. Usage example: ./git-split-subfolder.sh -p git://repo.com/foo -services -s mysubfolder -b "branch1 branch2 branch3" The new repo 'mysubfolder' will be in the $CWD.

	#!/bin/bash
	set -e

	usage() {
	cat << EOF
	usage: $0 [options]

	This script splits an existing folder inside of a git repo into its own
	separate git repo, optionally preserving all existing tags and branches from the
	parent repo.
