    利用指针实现Git版本还原
    # reset子命令用于版本还原
--soft：缓存区和工作目录不受影响，reset后分支和HEAD指针移动到指定的commit，代码文件和reset之前一样，修改部分已加入到暂存区，通常用于重新提交。
--mixed：（默认）工作目录不受影响，reset后分支的HEAD指针移动到指定位置，代码文件内容和reset之前一样，修改部分未加入到暂存区
--hard：工作目录，缓存区均受影响。reset后分支和HEAD指针移动到指定commit，代码文件内容回退到指定commit，工作空间为clean状态。通常用于获取指定版本的代码文件
# 还原到指定版本
[root@programer myproject]# git reset --hard 1c2535a7c2 
HEAD is now at 1c2535a modify test.txt
# 确认HEAD指针移动
[root@programer myproject]# git log --oneline
