What does "git checkout - ." do? -

i wanted revert local changes with

git checkout -- . 

but accidently did

git checkout - . 

and made lots of local modifications can't understand @ all.

what second command , possible revert done?

git checkout - checks out checked out branch. assume git checkout - . replace contents of working copy contents of checked out branch.

you can not undo that, since wanted reset contents of working dir anyways, why don’t run git checkout -- .?

you might want use git reset --hard in future undo changes against current branch. resets index.
