Tool to update a given git remote to change origin to github, instead of whichever it was tracking before. (in union with github desktop)

remoteupdate.sh

#! /bin/bash -e
# Note that this will echo the commands you need to run, review them before running. 
# It expects the process of 
# 1. Remove all origins, echo commands to add them again (somewhere that is not origin)
# 2. You add in github desktop the repo and click the button to add github as the remote
# 3. Copy paste the commands that were echoed before to readd the other origins after your repo is tracking github
