Command: reboot

The reboot command is used to restart the system. It initiates a shutdown sequence, terminating all running processes, unmounting filesystems, and then rebooting the computer. It requires superuser privileges to execute.

---

Sample Commands and Outputs:

• reboot: Reboots the system immediately. Sample Command and Output:

  $ sudo reboot

Description:

• sudo: Grants superuser privileges needed to reboot the system.
• This command will terminate all processes, unmount filesystems, and restart the machine.
• reboot -f: Forces an immediate reboot, bypassing the shutdown sequence. Sample Command and Output:

  $ sudo reboot -f

Description:

• -f: The option to force a reboot, which skips the normal shutdown procedures.
• Use this with caution, as it may result in data loss or filesystem corruption.
• reboot --halt: Halts the system without powering it off, useful for maintenance or diagnostics. Sample Command and Output:

  $ sudo reboot --halt

Description:

• --halt: The option to halt the system without restarting it.
• The system will stop all processes and freeze, requiring a manual power cycle to restart.

Note: The reboot command is essential for system administration, especially after making changes that require a full system restart to take effect. Always save your work and notify users before rebooting a system, especially in a multi-user environment, to avoid data loss or disruption.
