Git Basics you should know:

Setup

• git status shows the current state of your Git working directory and staging area.
• git config --list lists the git configuration
• git config --global user.name "MyLastname MyFirstname" set config for user name
• git config --global user.email "myemail@adress.com" set config for user email

Clone repo

• git clone https://myadress cloning a repo stored on Github/Bitbucket/…

Set branch

• git checkout <branchname> will change to other branch

Update repo

• git add myfilename adds a change in a file to the staging area
• git add directory/. adds changes in all files of a directory to the staging area
• git commit -m "this has changed" commit staged changes (add message)
• git push push changes to repo

Troubleshooting

• git reset will unstage all changes
• git reset HEAD^ to uncommit latest commit, keep file changes
• git reset --hard HEAD^ to remove latest commit and corresponding file changes
• If git config --list shows some entries you want to delete: use git config --unset-all <name>
• git push --force to make the remote repository match your local repo (attention, your remote repo will be overwritten!)
