difference between git pull --rebase and git rebase branch

Question

what is the difference between

• git pull --rebase
• git rebase origin/nameOfBranch

and when must use one over the other

Answer 1

The difference is that git pull does two things:

• fetch and
• merge (or rebase, since you give it the --rebase argument)

On the other hand, git rebase does only the rebase, not the fetch.
