You need to create a new user and give it sudo privleges:
        
        $adduser username
        Set password prompts:
        Enter new UNIX password:
        Retype new UNIX password:
        passwd: password updated successfully
        Changing the user information for username
        Enter the new value, or press ENTER for the default
        Full Name []:
        Room Number []:
        Work Phone []:
        Home Phone []:
        Other []:
        Is the information correct? [Y/n]
        
Give the new user sudo privledges 
        
        usermod -aG sudo username

Switch to new user 
        
        su - username
        
Then run

        Yo command
