Using git, how do you reset the working tree (local file system state) to the state of the index ("staged" files)?

I tend to use git checkout . which discards all changes from the working directory down. This makes a difference if you're not at the root of the repository.

This command doesn't remove newly created files which is usually a good thing. If you need to do this then you can use git clean as well.

You can use git stash save --keep-index to do this. After saving the stash, you can use git stash drop if you don't want to keep it around.

You can use git-checkout-index (git checkout-index). Be aware that you need to add

• -f to force it to overwrite existing files, or
• -f -a to enforce overwriting all paths in the index.
