Reset other branch to current without a checkout

Question

I\'m writing some scripts for my Git workflow.

I need to reset other (existing) branch to the current one, without checkout.

Before:

 Current         


        

Answer 1

You can sync with this command your branches at any time

$ git push . CurrentBranch:OtherBranch -f

Also without -f it replace this set of commands

$ git checkout OtherBranch
$ git merge CurrentBranch
$ git checkout CurrentBranch

It can be useful when you don't need commit all your files in CurrentBranch and so you can't switch to another branches.

Answer 2

Set otherbranch to point at the same commit as currentbranch by running

git branch -f otherbranch currentbranch

The -f (force) option tells git branch yes, I really mean to overwrite any existing otherbranch reference with the new one.

From the documentation:

-f
--force

Reset to if exists already. Without -f git branch refuses to change an existing branch.

Answer 3

The workflows you describe are not equivalent: when you perform reset --hard you lose all the changes in the working tree (you might want to make it reset --soft).

What you need is

git update-ref refs/heads/OtherBranch refs/heads/CurrentBranch
