Two important options for Linux-cd commands

Two important options of the Linux-cd command-Linux general technology-Linux technology and application information. The following is a detailed description. First Command: cd or cd ~ It is used to bring users back to their "root" directory. Eg. the root user calls cd or cd ~ Then use pwd to view the current working directory. The result is:/root. If I create a user pcwlno1 on Linux, no matter when I call cd or cd ~ I will return to/home/pcwlno1;

The second command: cd-this command allows you to return to the previous working directory. For example, I just jumped from/home/pcwlno1/eclipse/workspace to/usr/sbin/local/pppd. When I want to return to/home/pcwlno1/eclipse/workspace again, there is no need to call cd/home/pcwlno1/eclipse/workspace.

Cd. In this way, less physical labor can be done!

Give it a try.
