mm is the minute of the hour (two digits).
• Number of minutes to wait in the format +m, in which m is the number of minutes.

Procedure 4-20 Shutting Down Linux
From the command line for Red Hat Enterprise Linux or SuSE Linux Enterprise Server, issue the
shutdown command to shut down the OS.
1. Log in to Linux running on the system you want to shut down.
Log in to the management processor (MP) for the server and use the Console menu to access
the system console. Accessing the console through the MP enables you to maintain console
access to the system after Linux has shut down.
2. Issue the shutdown command with the desired command-line options, and include the
required time argument to specify when the operating shutdown is to occur.
For example, shutdown -r +20 will shut down and reboot the system starting in 20
minutes.
