Different ways to shutdown Ubuntu Linux using command line

Ubuntu Linux’s latest LTS version is 20.04, however, the commands to shutdown Ubuntu will work on all Linux versions. It doesn’t matter you are on Desktop or Server.

Indeed if we are using the Graphical user interface of Ubuntu Linux then we have GUI shortcuts to Power off, sleep, log out, or shut down the system. However, what about if we want to do the same using the command terminal. Yes, we can do all this from CLI as well.

From the command line we cannot only shut down our system but can schedule it along with other things on ubuntu, and all that we are going to show here.

If you want to shut down your system immediately, then simply type:

Schedule Shutdown

In case you want to power off your Linux system automatically but after some time then we can set that specific period of time in order to schedule the shutdown process.

shutdown -h time-in-number

shutdown -h 2

If you want to use any specific clock time for example 9:20 am, then we can do that as well, for that we use:

shutdown –h 9:20
