$ git log -3 --pretty=oneline

bbe630da410cda6fa910689cb92710309c12b540 commit3

King@ROYAL /d/gitworkspace/worktree/test (wgh_dev)

$ git revert HEAD

git reset

King@ROYAL /d/gitworkspace/worktree/test (wgh_dev)

$ git reset --soft HEAD~1

King@ROYAL /d/gitworkspace/worktree/test (wgh_dev)//--soft为默认值，被退回的修改会退到暂存区。

$ git status

$ git log -3 --pretty=oneline

bbe630da410cda6fa910689cb92710309c12b540 commit3 //可以看到没有添加一个类似 Revert "commit3"的提交，而是直接退到了commit3

0ff91e7df56e4505a012acb35cd2fe5bb184b24d commit2

62731c3c0bdfd2f169cff665d7cad6d3602718f2 commit1

King@ROYAL /d/gitworkspace/worktree/test (wgh_dev)//直接退回到了commit2，被退回的修改不会退到暂存区。

$ git reset --hard HEAD~1

HEAD is now at 0ff91e7 commit2
