Git Sync Fork - a shell script for syncing a fork of a repository to keep it up-to-date with the upstream repository

git_sync_fork.sh

#!/bin/bash
# 
# Before you can run this script, you must configure a remote that points to the upstream repository in Git.
# example from .git/config:
# ```
# [remote "origin"]
#	 url = git@github.com:naXa777/tutorials.git
#	 fetch = +refs/heads/*:refs/remotes/origin/*
# [remote "upstream"]
#	 url = https://github.com/eugenp/tutorials
#  fetch = +refs/heads/*:refs/remotes/upstream/*
# ```
