Check via shell-script if git repository's master branch is behind origin












0















I'm currently writing a bash script to remind me to rebase git repos when the local master branch is found to be behind origin/master.



I've been searching online for hours and no solution has worked.



So far I have come up with the following, but $? always returns 1 (I suspect this is because even an empty diff still loads less.



#!/bin/bash

REPO_PATH=$1
cd $REPO_PATH

# flow once inside repo
{
git fetch
git diff master origin/master
} &> /dev/null

if [ "" = $? ]
then
echo "Empty"
# logic to follow
else
{
git pull
} &> /dev/null
echo "Don't forget to rebase!!!"
echo $REPO_PATH
fi

# check for changes to master
# If master is behind origin/master
# then pull master and notify me to rebase

# run this at the start of the day (this script should be run from my start_work
# script and should also be periodically run throughout the day. [maybe every
# time I'm about to run coverage/push?])


Anybody have any ideas?



Sorry if this doesn't belong here, I wasn't sure whether to ask here or on Superuser.
