Check local repo changes before proceeding with other commands

git-safeguard.sh

#!/bin/bash
# Exits with error if there are uncommitted changes.
# This can be used as follows:
# $ ./git-safeguard.sh && <other commands>
# to only execute the other commands if there are no changes.
if [[ $(git status -s) ]]; then
	echo "There are uncommitted changes:"
	git status -s
	exit 1
fi

If you use some tool that pulls files from a service, you can use this safeguard to only proceed pulling if there are no local changes. This avoids files getting overwritten unexpectedly.

In my case I use this in the context of clasp pull (from Google), which I safeguard in my Makefile like so:

pull:
    ./git-safeguard.sh && clasp pull
