这篇文章主要介绍了linux中cd命令使用详解,总结的十分全面,这里推荐给小伙伴们。

 [root@localhost soft]# pwd
 /opt/soft
 [root@localhost soft]# cd ..
 [root@localhost opt]# cd ..//
 [root@localhost /]# pwd
 /

说明:
进入系统根目录可以使用“ cd .. ”一直退,,就可以到达根目录
命令:
cd ../.. //
输出:

复制代码 代码如下:


 [root@localhost soft]# pwd
 /opt/soft
 [root@localhost soft]# cd ../.. //
 [root@localhost /]# pwd
 /
 [root@localhost /]#
