How to see if local git repo and remote repo are same commit?
git fetch origin

git rev-parse master

git rev-parse origin/master

remote=$(
    git ls-remote -h origin master |
    awk '{print $1}'
)
local=$(git rev-parse HEAD)

printf "Local : %snRemote: %sn" $local $remote

if [[ $local == $remote ]]; then
    echo "Commits match."
else
    echo "Commits don't match."
fi

Local : 9e1b4dc286acb442f7f604be7916db660b9d70cd
Remote: 9e1b4dc286acb442f7f604be7916db660b9d70cd
Commits match.
