Git revert git branch command

Question

I am using Git version 2.27.0.

I made a mistake.

I was supposed to run this command to switch to another branch:

git checkout CTNG-52-flight-result-form-changes

But I ran this instead:

git branch CTNG-52-flight-result-form-changes

Problem

This has now created CTNG-52-flight-result-form-changes on my local repo. CTNG-52-flight-result-form-changes already existed on the remote repo, and now I don't want to make any changes to the remote repo, but I just want to checkout the remote repo branch (CTNG-52-flight-result-form-changes).

Question

How do I revert the git branch CTNG-52-flight-result-form-changes command without affecting anything on the remote repo?

More Info

Here is a log of my commands I ran:

Answer 1

With your git branch CTNG-52-flight-result-form-changes you have created a branch with name CTNG-52-flight-result-form-changes that doesn't track any remote branches, so you can delete it freely with following command:

git branch -d  CTNG-52-flight-result-form-changes

In order to checkout CTNG-52-flight-result-form-changes from the remote and set your local copy to track the remote, use this command:

git checkout -b  CTNG-52-flight-result-form-changes origin/CTNG-52-flight-result-form-changes
