For the life of me I can't seem to 'remove' an untracked sub-module/directory from the main git repository. I've tried various syntaxes, but I keep getting the 'pathspec' error stating there was no match, even though the folder is there in plain site. I added it to the .gitignore and it has not been added or committed to the main repository at all yet, but it keeps showing up in red under Untracked files: when I run git status and I can't get rid of it. git clean -n shows nothing either.
Any clues as to what I'm doing wrong here?
To be clear: I don't want to delete the sub-repo, I merely want to track the sub-repo entirely separately and have the main-repo totally ignore it as if it does not exist.
