Unstage a deleted file in git

Question

Usually, to discard changes to a file you would do:

git checkout -- 

What if the change I want to discard is deleting the file?

Answer 1

If it has been staged and committed, then the following will reset the file:

git reset COMMIT_HASH file_path
git checkout COMMIT_HASH file_path
git add file_path

This will work for a deletion that occurred several commits previous.
