Guidelines for Shutting Down a System

    Keep the following in mind when you shut down a system:

  • Use either the shutdown or the init command to shut down a system. Both commands perform a clean system shutdown, which means all system processes and services are terminated normally.

  • You need to be the root role to use the shutdown and init commands.

  • Both the shutdown and init commands take a run level as an argument.

      The three most common run levels are as follows:

    • Run level 3 – All system resources are available and users can log in. By default, booting a system brings it to run level 3, which is used for normal day-to-day operations. This run level is also known as the multiuser state, with NFS resources shared.

    • Run level 6 – Shuts down the system to run level 0, and then reboots the system to a multiuser level with SMB or NFS resources shared (or whatever run level is the default in the inittab file).

    • Run level 0 – The operating system is shut down, and it is safe to turn off power. You need to bring a system to run level 0 whenever you move a system, or add or remove hardware.

    Run levels are fully described in How Run Levels Work.
