Running a Command on Server Startup using Cron Job

Introduction

Instructions

Using sudo in .profile for fwconsole restart

You can add sudo to the command in your .profile file if the fwconsole restart command requires elevated privileges.

Here's how you can modify the command to include sudo:

sudo /usr/bin/fwconsole restart

Make sure that the user running the command has appropriate permissions in the sudoers file (/etc/sudoers) to execute fwconsole restart with sudo without being prompted for a password.

After adding the sudo prefix to the command, save the changes to your .profile file, and the fwconsole restart command will be executed with elevated privileges the next time you log in.
