To run a shell script automatically at Ubuntu startup, you can employ a startup application tool called “cron”. Here’s how you can accomplish it:

First, open a terminal and enter the following command to open the cron configuration file:
“`
crontab -e
“`
If asked to select an editor, choose your preferred one (nano, vim, or any other available).

This command opens the cron configuration file in the editor. Add the following line at the end of the file to run a script named “script.sh” at startup:
“`
@reboot /path/to/script.sh
“`
Replace “/path/to/script.sh” with the actual path to your script. Save the file and exit the editor.

Now, your shell script will execute every time Ubuntu starts up.
