This article will explain in detail about the use of linux's su command to switch users. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The su command is used to switch the current user identity to a specified user or to execute a command or program as a specified user.

Ordinary users switch to root users and can use su-- or su root, but must enter a root password to complete the switch. Root users switch to ordinary users and can use su username without entering any password to complete the switch.

Syntax format: su [option] [user name]

Common parameters:

Reference example

Switch to linuxcool user, but the environment variable is still root user:

[root@linuxcool ~] # su linuxcool

Switch to the linuxcool user and change to the linuxcool user environment variable:

[root@linuxcool ~] # su-linuxcool

Change the account to root and pass the-f parameter to the newly executed shell:

[root@linuxcool] # su root-f so much for switching users using linux's su command. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
