GIT commands


A deliberately minimal set of commands for using GIT as simply as possible. Note:

  1. GIT will ask for some details the first time you use it on a machine
  2. these instructions will need a repo on GitHub for you to push to
  3. don't create a readme.md file on GitHub, make it locally and push

Setup a new repository

  1. git init
  2. git status
  3. git add .
  4. git commit -m "describe change"
  5. git status
  6. git remote add origin URL_of_remote_repo_here
  7. git remote -v
  8. git push -u origin master

Work on another machine

  1. git clone URL_of_remote_repo_here
  2. (do some work)
  3. git add .
  4. git commit -m "describe change"
  5. git status
  6. git push

Use a branch to test new code

  1. git checkout -b branchname_here
  2. (do some work)
  3. git add .
  4. git commit -m “describe change”
  5. (repeat 2-4)
  6. git push -u origin branchname_here
  7. git checkout master
  8. git diff master branchname_here
  9. (repeat 2-4 if necessary)
  10. git merge branchname_here
  11. (repeat 2-4 if necessary)
  12. git branch -a (lists all branches)
  13. git branch -d (use -D to force delete)

Check history and rewind

  1. git log --pretty=oneline
  2. git fetch origin (override local changes)
  3. git reset --hard origin/master
  4. git checkout -- filename_here (restore previous version of file)
  5. git reset —hard HEAD~ (revert to previous commit)

Change remote

  1. git clone URL_of_remote_repo
  2. git remote set-url origin URL_of_NEW_repo
  3. git remote -v
