when u commit and then realize that yo have not pulled from remote.Follow these steps to avoid adding an extra merge commit to your branch and keep the commits clean.

git1.md

Say the branch in which you were working was : master

git add -A
git commit -m "added few changes"
commit hash = 5e108f2

you added your work and then committed it. But then realised you forgot to pull.Now:
git checkout -b newtry master
// git checkout newtry -->optional : try without this

git branch -d master /git branch -D master (force delete)

git pull origin master

git checkout master

git cherry-pick 5e108f2

git push origin master

git branch -d newtry/git branch -D newtry

Great post @miss-invincible !!
