git reset or clean or checkout didn't work [duplicate]

For all unstaged files in current working directory use:

git checkout -- .

For a specific file use:

git checkout -- path/to/file/to/revert

-- here to remove ambiguity (this is known as argument disambiguation).

For Git 2.23 onwards, one may want to use the more specific

git restore .

resp.

git restore path/to/file/to/revert

that together with git switch replaces the overloaded git checkout (see here), and thus removes the argument disambiguation.

Another quicker way is:

git stash save --keep-index --include-untracked

You don't need to include --include-untracked if you don't want to be thorough about it.

After that, you can drop that stash with a git stash drop command if you like.

It seems like the complete solution is:

git clean -df
git checkout -- .

git clean removes all untracked files (warning: while it won't delete ignored files mentioned directly in .gitignore, it may delete ignored files residing in folders) and git checkout clears all unstaged changes.
