Shutting Down the System to Single-User Mode

In some cases, you might need to shut down the system and enter single-user mode to perform software maintenance and diagnostics.

1. Type cd / to change to the root directory. You must be in the root directory to shut down the system to single-user mode to ensure that file systems are unmounted cleanly.
2. Type shutdown -m. The system shuts down to single-user mode. A system prompt displays and you can perform maintenance activities.
