How Do I Schedule an Auto Shutdown in Ubuntu?

Setting up an auto shutdown in Ubuntu is a straightforward process, and it can be achieved using different methods. Let’s delve into the details of each approach:

Method 1: Using the Terminal

The terminal provides a powerful way to schedule tasks in Ubuntu. To set up an auto shutdown using the terminal, follow these steps:

  1. Open the terminal using the shortcut Ctrl + Alt + T.
  2. To schedule a shutdown after a specific time, type the following command:
sudo shutdown -h +m
  1. Replace m with the number of minutes after which you want the shutdown to occur.
  2. To schedule a shutdown at a specific time, use the following command:
sudo shutdown -h hh:mm
  1. Replace hh:mm with the desired time in hours and minutes.

Method 2: Using the GNOME Scheduler

Ubuntu’s default desktop environment, GNOME, offers a user-friendly way to schedule tasks, including shutdowns. Here’s how to do it:

  1. Open the “Scheduled Tasks” application. You can find it by searching for “Scheduled Tasks” in the applications menu.
  2. Click the “+” button to add a new task.
  3. In the “Command” field, enter:
/sbin/shutdown
  1. Add the desired arguments to the “Command” field to specify the shutdown time. For example, to shut down after 30 minutes:
-h +30

To shut down at a specific time (e.g., 10:00 PM):

-h 22:00

Method 3: Using Cron Jobs

Cron jobs are automation tasks that can be scheduled to run at specific intervals. To set up an auto shutdown using cron jobs:

  1. Open the terminal.
  2. Type the following command to edit your cron jobs:
crontab -e
  1. Add a new line to schedule the shutdown. For example, to shut down every day at 11:30 PM
