I'm new in git. Now I'm using Github Codespaces, the online IDE provided by Github. I code in a workspace affiliated to a Github repo, however I don't know how to upload my file in the Codespaces to the corresponding repo. Each time I click commit, the IDE tells me that there is no change so the commit is cancelled.
I wonder if there is a git command to upload my script, or any other method. Any help would be appreciated！
