git: What if a second branch tracks another branch in origin?

Question

What are the consequences of having a remote branch with the same origin as another one?

For example

   // Create branch foo but track origin/bar instead of origin/foo
   git branch --track foo origin/bar
   git push origin foo

What are the side effects of such links?

Answer 1

It doesn't cause any side effect. It is just the name you have given to your local branch.

But depending on your config, you will have to do:

git push origin foo:bar

otherwise it will create a new branch ( or push to a branch) of name foo

Alternatively, add the following to .git/config:

[push]
    default = tracking

or do git config push.default tracking
