Hi,

i don't clearly understand the difference between Fetch vs Pull.

When we need to do a fetch and When we need to do a pull

I understand we need to use Pull to pull the updates or new changes or updated changes from git

Thanks

Moved to our “General Computing” forum.

Can you find a Git tutorial anywhere, or a book like this one? I think Manning are giving a 50% discount on all eBooks until late May.

git pull is just a shorthand for git fetch + git merge.

With fetch, you get the changes from the remote server and synchronize your origin branch. With pull, you additionally merge the origin branch to your local branch.

Fetch is useful if you want to see what changes have been made on the remote server, without making any changes to your local copies.

git pull literally performs a fetch first, so that part of the behavior is identical.

What did you do to test this? If you performed git pull immediately after a git fetch, obviously the fetch step from the pull command won't have any result, because all the work has already been done by the first time git fetch was called.

So which one is always good when i want to update a project...that's where the confusion is...

Git pull or Git fetch....Many uses Git Pull..Some uses Git Fetch...since GIT fetch updates the branches list as well....

Like I said, fetch only updates the origin branches. An origin branch is a local representation of the branch on the remote server. You're not supposed to do any work on them. I'm not even sure to can commit or merge anything to those branches.

Like fetch, pull ALSO updates the origin branches because, as I said, it literally first performs a fetch.

The ONLY difference is that pull merges the fetched branches to the currently checked out branch, so you can continue work on the changes you fetched from the remote server.
