How to Restart Ubuntu Linux: A Complete Guide
Restarting Ubuntu Linux involves shutting down and then immediately starting the operating system again. This action closes all running programs and clears the system’s temporary memory, which can fix minor glitches or apply updates.
You can restart Ubuntu from either the command line or the desktop interface. For instance, typing sudo reboot in the terminal command line requires administrator permissions to execute and immediately restarts your system.
On the desktop, a simple restart is possible by clicking the system status area in the top-right corner of your screen. From there, select the power icon, and then choose the “Restart” option from the menu that appears.
Restart Ubuntu Linux using the system menu by clicking the top-right status area, selecting the power icon, and choosing “Restart.” Alternatively, open a terminal and type `sudo reboot` or `sudo shutdown -r now`.
How to restart Ubuntu Linux from the system menu
The system menu on your desktop offers a quick way to restart.
To restart in Ubuntu Linux, click the top-right of the system menu, then choose Power Off / Log Out to expand the context menu.
Select ‘Restart’ from the expanded menu, and then click the ‘Restart’ button.
Restart Ubuntu Linux from the command line
If you prefer the Ubuntu Linux command line, open it by pressing Ctrl+Alt+T on your keyboard and run the commands below to restart your PC.

You can also schedule a restart using the 24-hour format with the shutdown command, like this example: restart at 5:00 PM

The command line also allows specifying a wait time before shutdown, for instance, to restart in 15 minutes. Use the command options below:
sudo shutdown -r +15
