7 Efficient Ways to Restart Linux from the Terminal

Restarting Linux from the terminal is simpler than it seems. It is essential, especially after updates, troubleshooting, or system maintenance, to ensure your system remains stable. This guide will explore various methods to restart your Linux system through the terminal.

1. Using the reboot Command

The reboot command is one of the simplest ways to restart your Linux system. It safely terminates all running processes to prevent data loss. To reboot immediately, enter:

sudo reboot

For a forced reboot, you can use the -f option:

sudo reboot -f

2. Using the shutdown Command

The shutdown command can also be used for immediate or scheduled reboots. To reboot your system immediately, execute:

sudo shutdown -r now

For a scheduled reboot after a specified time, like two hours:

sudo shutdown -r +120

If you need to cancel a scheduled reboot, run:

sudo shutdown -c

3. Using the systemctl Command

If your system utilizes systemd, the systemctl command is the recommended method:

sudo systemctl reboot

4. Using the init Command

Older distributions that use SysVinit can restart with:

sudo init 6

This command shifts to runlevel 6, signaling the system to reboot.

5. Using the telinit Command

Similar to init, the telinit command can be used to restart the system:

sudo telinit 6

6. Using REISUB (Magic SysRq Key)

In case your system is unresponsive, the REISUB key sequence is a safe method to reboot without risking data corruption. Press Alt + SysRq (Print Screen) together, then sequentially press:

• R (Raw mode)
• E (Terminate processes)
• I (Kill processes)
• S (Sync disks)
• U (Remount filesystems as read-only)
• B (Reboot)

7. Restarting Linux via SSH

When managing a Linux server remotely, connect using SSH:

ssh user@your-server-ip

Once connected, you can reboot the system immediately:

sudo reboot

To schedule a reboot, type:

sudo shutdown -r +10  # Reboots after 10 minutes

To cancel a scheduled reboot, use:

sudo shutdown -c

Conclusion

Restarting Linux from the terminal is not only straightforward but also versatile, offering methods to fit various scenarios like immediate, scheduled, or even forced reboots. Familiarity with these commands empowers you to manage and troubleshoot your Linux systems efficiently.
