To automatically shut down a Linux system after a certain period of time, you can use the "shutdown" command with the "-t" option, which specifies the number of seconds until the system should be shut down. For example, to shut down the system after 3 minutes, you can use the following command:

In perl:-

sudo shutdown -h +3
This command will shut down the system after 3 minutes. The "-h" option is used to specify that the system should be halted (or shut down) after the specified time.

You can also use the "at" command to schedule a shutdown for a specific time. For example, if you want to shut down the system at 6:00 PM, you can use the following command:

In bash:-

echo "shutdown -h now" | at 18:00
This will schedule a shutdown for 6:00 PM.

Note that using the above commands will require root or superuser permission.
Also, please be careful when using the shutdown command, as it will immediately shut down the system and any unsaved work will be lost.
