Run a Linux command after every reboot

[Guest Challenger.]

This tip allows you to run any Linux command or script just after system reboot. You can use the @reboot cron keyword.
If you have a script in your /home directory and it needs to be run on every boot, open the cron file in editable mode and add the following:

$crontab -e

@reboot /home/xyz/myscript.sh

Do remember to enable crond on boot.
