How to create a new branch on both local and remote? GIT [duplicate]

I create a new branch like this:

git branch dev-itt-9

However, it only creates a new branch on local

git branch -a

* dev-itt-9
  master
  testing

  remotes/origin/HEAD -> origin/master
  remotes/origin/development
  remotes/origin/master
  remotes/origin/testing

What is the proper way to create a new branch on both local and remote?

I am quite new to git. Sorry if my question is stupid.

First, you create your branch locally:

git checkout -b <branch-name>

The remote branch is automatically created when you push it to the remote server. So when you feel ready for it, you can just do:

git push <remote-name> <branch-name>

Where <remote-name> is typically origin, the name which git gives to the remote you cloned from. Your colleagues would then just pull that branch, and it's automatically created locally.

Suppose you already created your local branch (using git branch <branch-name> or git checkout -b <branch-name>, you can use:

git push -u origin <branch-name>

explications:

• -u = --set-upstream : set this new remote branch as tracking branch.
• origin : the name of your remote repository
