Centos command notes

The first thing after installing the system is to update the system.

1. Use the yum command to update Yum update

2. The su command is one of the most basic commands and is often used for switching between different users,

Exit to exit the current user.

3. Like the Dir command in DOS, the LS command is used to display the contents of the current directory. If you want to obtain detailed information, you can use the LS-l command to display detailed information about the directory content. If the directory contains too many files and cannot be displayed on one screen, use LS-L | more split screen.
