git undo delete-Unstage a deleted file in git

Question

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

git checkout -- <file>

What if the change I want to discard is deleting the file? The above line would give an error:

error: pathspec '<file>' did not match any file(s) known to git.

What command will restore that single file without undoing other changes?

Answer 1

For this question, you need to undo the effects of 

git rm <file> 

or

 rm <file> followed by git add -A 

To restore the file status in the index

git reset -- <file>

To check out a copy from the index

git checkout -- <file>

To undo git add <file>, the first line of the code will meet your needs, assuming you haven't committed yet.
