command line - git undo all commited changes / Stack Overflow http://stackoverflow.com/questions/14075581/git-undo-all-uncommitted-changes

git-undo.sh

# This will unstage all files you might have staged with git add:
git reset

# This will revert all local uncommitted changes (should be executed in repo root):
git checkout .

# You can also revert uncommitted changes only to particular file or directory:
git checkout [some_dir|file.txt]

# Yet another way to revert all uncommitted changes (longer to type, but works from any subdirectory):
git reset --hard HEAD

# This will remove all local untracked files, so only git tracked files remain:
git clean -fdx
