I ran a git command, I'm afraid I did something terrible, can you see?

Question

git

git pull origin letters_site
I wanted to download a branch from the repository, but the branch was not created, later I found out that the branch was downloaded differently git checkout -b <branch name> origin/<branch name>
What did I do?

Answer 1

froze changes from origin, the letters_site branch to its working copy on the local branch, the name of which can be viewed via git status

Answer 2

In order not to change anything, but just to watch new commits, you can get branches via git fetch. (git pull is git fetch + git merge)
