Prompt Title: add newuser

Here are the steps to create a new non-root user with their own home directory and sudo privileges:

1. Log in to the server as the root user or a user with sudo privileges.

2. Create a new user account using the following command, replacing "newusername" with the desired username:

   Copy code
   adduser newusername
   

3. Set a password for the new user when prompted.

4. Create a new directory for the user's home directory with the following command, replacing "newusername" with the desired username:

   arduinoCopy code
   mkdir /home/newusername
   

5. Set the correct permissions for the new home directory with the following command:

   bashCopy code
   chmod 755 /home/newusername
   

6. Change the ownership of the new home directory to the new user with the following command, replacing "newusername" with the desired username:

   bashCopy code
   chown newusername:newusername /home/newusername
   

7. Grant sudo privileges to the new user by adding them to the "sudo" group with the following command:

   Copy code
   usermod -aG sudo newusername
   

8. Log out of the root or sudo user account.

9. Log in to the server with the new username and password.

10. Test sudo privileges by running a command with sudo, such as:

    bashCopy code
    sudo ls -la /root
    

    You should be prompted for your password and then see the contents of the root directory.

That's it! You have successfully created a new non-root user with their own home directory and sudo privileges.
