1、把远程仓库克隆到本地

root@virtualbox:/home/wwwroot# git clone https://gitee.com/liu21st/thinkphp.git
root@virtualbox:/home/wwwroot# git clone https://gitee.com/liu21st/thinkphp.git thinkphp6
root@virtualbox:/home/wwwroot# ll
总用量 16
drwxr-xr-x  4 root root 4096 11月 27 17:22 ./
drwxr-xr-x  6 root root 4096 11月 20 16:34 ../
drwxr-xr-x 11 root root 4096 11月 27 17:21 thinkphp/
drwxr-xr-x 11 root root 4096 11月 27 17:22 thinkphp6/
root@virtualbox:/home/wwwroot# cd thinkphp

2、Git分支管理命令

• 查看当前分支：git branch
• 切换Git分支：git checkout branchname
• 删除Git分支：git branch -D branchname

3、管理Git分支上的文件

• 拉取最新版本：git pull
• 舍弃当前目录所有的更改：git checkout .
• 舍弃当前目录某个文件的更改：git checkout filename

4、Git回滚代码

• 查看Git日志：git log

root@virtualbox:/home/zhenkai/thinkphp# git log
