This will unstage all files you might have staged with
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):虽然在调用时加上
git reset成为一个危险的命令（译注：可能导致工作目录中所有当前进度丢失！），但本例中工作目录内的文件并不会被修改。 不加选项地调用
git reset并不危险 — 它只会修改暂存区域。
git reset --hard HEAD
This will remove all local untracked files, so only git tracked files remain:
git clean -fdx
-xwill also remove all ignored files!
To sum it up: executing commands below is basically equivalent to fresh
git clone from original source (but it does not re-download anything, so is much faster):
git reset git checkout . git clean -fdx
Typical usage for this would be in build scripts, when you must make sure that your tree is absolutely clean - does not have any modifications or locally created object files or build artefacts, and you want to make it work very fast and to not re-clone whole repository every single time.
