Yesterday I did
git add .
$ git status
On branch develop
Your branch is behind 'origin/develop' by 5 commits, and can be fast-forwarded.
(use "git pull" to update your local branch)
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
no changes added to commit (use "git add" and/or "git commit -a")
If you did not
git add and therefore did not
git commit, and just want the state to look like yesterday, a simple hard reset will fix it.
git reset --hard
