Check if pull needed in Git

Question

How do I check whether the remote repository has changed and I need to pull?

Now I use this simple script:

git pull --dry-run | grep -q -v \'Already          


        

Answer 1

Using simple regexp:

str=$(git status) 
if [[ $str =~ .*Your\ branch\ is\ behind.*by.*commits,\ and\ can\ be\ fast-forwarded ]]; then
    echo `date "+%Y-%m-%d %H:%M:%S"` "Needs pull"
else
    echo "Code is up to date"
fi
