Git: restoring accidentaly deleted files

To view a list of deleted files:

git ls-files --deleted

To restore a deleted file (assuming the D is not yet commited)

git checkout where/the/file/was.ext

custom assert_select_rjs matcher

Background:

Therefore this will work:

Obi-Wan vs Yoda

I just realized this the other night while watching The Amazing Race though it seems to have been talked about since Episode 3 was released.

Obi-Wan:
Only a Sith deal in absolutes

Yoda:
Do, or do not. There is no try.
