GIT入门笔记（11）- 多种撤销修改场景和对策--实战练习

1、检查发现目前没有变化
$ git status
On branch master
nothing to commit, working tree clean

$ cat lsq.txt
2222

2、修改文件并add

$ echo "3333" > lsq.txt
$ git add lsq.txt
warning: LF will be replaced by CRLF in lsq.txt.
The file will have its original line endings in your working directory.

3、接着修改
$ echo "4444" > lsq.txt
$ cat lsq.txt
4444

4、用checkout撤销add后的修改
$ git checkout -- lsq.txt

$ cat lsq.txt
3333

5、用reset恢复stage区到Head，然后checkout到工作区

$ git reset HEAD lsq.txt
Unstaged changes after reset:
M lsq.txt

$ cat lsq.txt
3333

$ git checkout -- lsq.txt

$ cat lsq.txt
2222

6、检查历史版本号
$ git reflog lsq.txt
9ff99f2 HEAD@{0}: commit: 2222
9104638 HEAD@{1}: commit: 11111

7、回退到commit的历史版本
$ git reset --hard 9104638
HEAD is now at 9104638 11111

$ cat lsq.txt
1111111
