I got annoyed having to git add then git commit -a -m and then git push most of the time, so here's a shortcut.
Having to remove the quotes and re-add them was also annoying.

Add to /home/yourname/.bashrc

# add files, commit "my message" and push
function save {
  git add .
 git commit -a -m "$*"
