Yes, you can schedule tasks to run at startup or after a system reboot using the "@reboot" keyword in your crontab entry. For example, to run a script called "myscript.sh" at startup, you would add the following line to your crontab file: "@reboot /path/to/myscript.sh". This will ensure that the script runs every time the system boots up. There’s no limit to what you can build and automate.
