Git Cheat Sheet

Note: With all the commands below you can see the result of your actions (by looking at the commit graph)[https://github.com/DUWS-R-Team/DUWS-R/network] for GitHub or you can run the following command from your Git Bash to get something very similar. git tree = log --graph --decorate --pretty=oneline --abbrev-commit --all

Letting my local repository know about DUWS-R

• For SSH git remote add upstream [email protected]:DUWS-R-Team/DUWS-R.git
• For HTTP git remote add upstream https://github.com/DUWS-R-Team/DUWS-R.git

Creating a new branch

• git checkout master - Put me on my master branch
• git checkout -b MyNewBranchName - Create a new branch based off my master

Getting a branch to use the latest version of code from DUWS-R

• Updating local master
  • git fetch upstream - Let my local know about the changes on DUWS-R
  • git checkout master - Put me on my master branch
  • git rebase upstream\master - Bring my local master up to match the upstream master
• Updating another branch (perform the above steps first)
  • git checkout MyBranchName - Put me on my branch
  • git rebase master - Update me to my master
    • If you have problem here you most likely need to merge or abort
      • Some merge tools can be found here
      • You can abort by typing git rebase --abort
      • You can merge by following this guide

Cleaning up 'old' branches that have been removed by things such as merging or deleting branches on GitHub

• Letting your local repository know that a branch was deleted from GitHub
  • git fetch upstream -p
• Removing local branches that have been merged into upstream
  • git branch --merged | grep -v "\*" | egrep -v "master" -- Prints what branches would be removed if you run the command below containing xargs
  • Make sure you are okay with the branches listed being deleted -- This can be undone by using git's reflog but that will not be covered here
  • git branch --merged | grep -v "\*" | egrep -v "master" | xargs -n 1 git branch -d -- Delete the branches that were listed by the first command above.
