I made changes to some of my files in my local repo, and then I did
git add -A which I think added too many files to the staging area. How can I delete all the files from the staging area?
After I do that, I'll just manually do
git add "filename".
You can unstage files from the index using
git reset HEAD -- path/to/file
git add, you can unstage files recursively by directory and so forth, so to unstage everything at once, run this from the root directory of your repository:
git reset HEAD -- .
Also, for future reference, the output of
git status will tell you the commands you need to run to move files from one state to another.
