To check which branch you are on

• Type: git status (git automatically creates a master branch on a new repo)

To check in which branch the head is pointing

• Type: git log --all --decorate --oneline --graph (the head points to a branch and not necessarily to a commit. It tells us what we have checked out)
• Type: alias graph="git log --all --decorate --oneline --graph" (this creates a reusable command alias called graph that saves the above options and makes it shorter to type)

To create a new branch where the head pointer is

• Type: git branch ... ("..." is the name of the branch that will be created)
• Type: git branch (shows an star next to the branch that is checked out or that the head point to)

To switch branch and head pointer

• Type: git checkout ... ("..." is the name of the branch that will be switched to. The head will point to that)

To merge the changes into a master branch

• Type: git merge ... ("..." is the name of the branch to catch-up to from the head)
• Type: git branch --merged (shows us which branches are merged together)

To delete a branch

• Type: git branch -d ... ("..." is the the name of the branch to delete)
