Git asks me to commit or stash changes on checkout master, even though all changes were committed?

I encountered a similar problem today. git status wasn’t listing the files which checkout was complaining about. I did a:

git checkout -- path/to/file

And that undoes any changes to the file.

An even easier way to undo all unstaged changes on current working directory [1]:

git checkout -- .

[1] – Be warned – you will lose any other unstaged changes you were working on (if any). If you don’t know what you are doing, then keep a backup of the files you were working on 🙂
