BASH script to change "original" upstream clone to newly forked repo

git-forked-to

#!/bin/bash

## If you cloned a repository, then forked it and want to change your clone to point to your fork...
## Usage:
##    git-forked-to <NEW ORIGIN URL> [<BRANCH>]
##
## <NEW ORIGIN URL> should be your new forked repo URL
## <BRANCH> defaults to "master"
##
## For example:   git-forked-to git@github.com:SHaTRO/conveyance.git
##
## Thanks to James Gregory (https://gist.github.com/jagregory/710671) for his notes
## In his (jagregory's) words:
##   Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked.
##

# So here it is, developed under git v.1.9.1; should work for git >= 1.8.0

ORIGIN=${1}
BRANCH=${2:-master}

echo -n "Renaming 'origin' to 'upstream': " && git remote rename origin upstream && echo "done." && \
echo -n "Adding 'origin': " && git remote add origin ${ORIGIN} && \
git fetch origin && \
( git branch -d origin/${BRANCH} || echo "But that is ok, we will assign it as upstream now" ) && \
git branch --set-upstream-to origin/${BRANCH} ${BRANCH} && \
echo -n "Pulling: " && git pull && \
git status

Thanks, @jagregory for the notes at "How to move to a fork after cloning"!

Works like a charm, thanks!
