Git fetch remote branch and remote ref

Question

how do i get the remote branch and update the local git link for this branch without executing the current branch? For example, if I do this

$ git pull origin master 

origin / master merges into my current branch. This also does not work.

 $ git fetch origin master 

How then do I check

 $ git branch -r -v origin/HEAD -> origin/master origin/master 7cf6ec5 test 02 

that origin / master ref "7cf6ec5 test 02" is lagging. The true origin / master is "XXXXXX test 03". git fetch only pulled the changes to FETCH_HEAD, it did not load the local origin / master ref. What is the step to update this ref?

Note:

 $ git fetch origin 

Get all deleted links and update them, but unfortunately (a) a lot of mess. (I don’t want someone else 30-50 random branches to know that someone will not want mine) and (b) when the branches are deleted by origin, these links are not deleted locally the next time I do git fetch origin , which means this path ends abruptly.

The question is, how to extract only one branch and update its ref locally?

Answer 1

I think I'm looking for it

 $ git fetch origin master:refs/remotes/origin/master 

This is similar to the fact that unlike 'w10> origin master' I really see that ref is being updated.

Any reason why the answer is wrong? Something I should be afraid of?

Answer 2

 git fetch origin 

this will delete all the remote branches and update the remote tracking branches for them.

You can now do one of two things.

 git checkout other-branch git merge origin/other-branch git checkout - 

or

 git push . origin/other-branch:other-branch 

The last option is fine, if you know that it will be a quick merge forward.

Answer 3

You can always specify refspec for the git fetch command. In particular, if you want to update other-branch , you can do:

 git fetch origin other-branch:other-branch 

This will extract the current tip of refs/heads/other-branch from the source and put it in a local branch with the same name.

Another way: continue and:

 git fetch origin other-branch 

And then recreate the local branch:

 git branch -l -f other-branch -t origin/other-branch 

-l exists as a security mechanism. It will create a reflog entry so that you can revert to the previous version if you need to.
