Hello everyone, welcome back to your own channel Technical Sahil. In this video, I show you how you can assign sudo privileges to a user on an Ubuntu system using the command line. I’m continuing from the previous setup where I created a normal user (in my case, “sahil”), and now the goal is to elevate permissions properly so you can manage your server smoothly without staying logged in as root all the time. First, I switch to the root user (either login as root directly or use `su` and enter the root password). After that, I use the exact command `usermod -aG sudo sahil`—this modifies the user and adds them to the sudo group, which is what actually grants sudo access. Then I verify it using `groups sahil` so you can confirm the user is now inside the sudo group. I also show you a common issue where you might still get “not in the sudoers file” right after changes—so I simply logout and login again, and then `sudo whoami` works properly. By the end, you’ll understand how to grant sudo safely, verify it, and test access (even checking root directory access) on Ubuntu.
