Initialize a new git repository:
in target folder execute:
git init


How to add a local ssh key to GitHub:
generate ssh key on Linux VM:
ssh-keygen

copy the public key from target folder, by default /home/username/.id_rsa.pub
cat /home/username/.id_rsa.pub

paste key to GitHub:
user settings —> SSH and GPG keys —> New ssh key

Add remote repository:
git remote add origin git@github.com:username/repository_name.git

Check on what branch you are:
git branch

Check what local and remote branches git knows about:
git branch -a

Switch to the existing branch:
git checkout "existing-branch-name"

Create a new branch:
git checkout -b "new-branch-name"

Push the new branch to remote:
git push -u origin "new-branch-name"

Create an existing branch and move HEAD there:
git checkout -b "new-branch-name" "existing-branch-name"

Fetch all info about remote branches:
git fetch --all

Diff one branch against another:
git diff master..staging

Rename git branch:
git branch -m "existing-branch-name" "new-branch-name"

Help and man:
git help branch
git branch --help
man git-branch

Delete a branch:
git branch -d "branch-name-to-delete"


Forcefully delete a branch (think twice before using it):
git branch -d --force "branch-name-to-delete"

Full new feature flow:
# Start a new feature
git checkout -b new-feature master

# Edit some files
git add <file>
git commit -m "Start a feature"

# Edit some files
git add <file>
git commit -m "Finish a feature"

# Merge in the new-feature branch
git checkout master
git merge new-feature
git branch -d new-feature
