Getting Git

A comprehensive video course from git init to Git Master.

Master: git fetch

In this video we'll learn some of the additional options for git fetch.

In init: git fetch, we covered how to use git fetch to fetch from a single remote.

If we have multiple remotes, we can use the --all option to fetch for all remotes.

We can do so by running:

git fetch --all.

In this case, it will download information from both the origin and upstream remotes.

To fetch from multiple remotes, but not all of them, we can use the --multiple option.

For example, if I didn't want to fetch from all remotes, but specifically the origin and upstream remote, I could run:

git fetch --multiple origin upstream

The final option we'll learn is --prune.

Over time, you'll build up a lot references. By default, git fetch does not remove local references that no longer exist on a remote.

To do so, you have to add the --prune option.

Let's demonstrate this by pushing a test branch to GitHub.

Then we'll remove the test branch on GitHub.

If I run git fetch origin, notice nothing is updated.

If I run git log --oneline --decorate --graph --all, we still see a local reference to origin/test.

However, if we run git fetch --prune origin, we see from the output it deleted the test branch, and we can verify it no longer appears when running git log.
