My git cheat sheet

• Update commit message
  

  git commit --amend -m "correct commit message"

• Create and start track remote branch
  

  git checkout -b branch_name
  git push origin branch_name
  git branch --set-upstream branch_name origin/branch_name

• Delete a commit you a sitting on (not yet pushed)
  

  git reset --hard HEAD~1

• Delete remote branch and stop track it
  

  git push origin --delete branch_name
  git branch -d branch_name
  git remote prune origin

• Reset the index and working tree
  

  git reset --hard

• Find all branches which can be safely deleted, since those branches are fully contained by HEAD
  

  git branch -r --merged
