git撤销操作

git有如下三种状态：

• Modified: You have changed the file but have not committed it to your database yet.
• Staged: You have marked a modified file in its current version to go into your next commit snapshot.
• Committed: The data is safely stored in your local database.

现在主要讲述下git的撤销操作：

discard changes in working directory

前提：<file>已经被添加到暂存区

git restore <file>

working direction <- index

git reset HEAD <file>

index <- HEAD

git reset --soft HEAD^

working direction <- HEAD

git reset --hard HEAD^
