    Sorry, but this article is poorly written. You su to root and then show most of the commands as root. You don’t show whether the “home” directory is “/root/“, for root, or “/home/user/” for the regular user! Then later, you are logged in as a regular user when you show the “history” command in the image.

    You should show you are logged in as root (“#”) ONLY for those command that you NEED to be logged in as root, and as a regular user (“$”) for everything else!

    The other problem with the “su” command, is that Ubuntu and other “Toy” Distros have the “su” command disabled, and force the user to us “sudo” instead. You should instruct those users how to re-enable “su” with the command:

    "$ sudo passwd root" 
    

    Press enter, and type in a new password for root, twice.

    Also, you should have changed your prompt to show exactly what directory you are currently in, for illustration purposes!

      Good concern, but you’ll notice that all the commands here where run as root, therefore the home folder is for the root(/root). The only sub section where we used a normal user login is when we explained shell invocation in interactive non login mode(using su to switch to root user or another user).

      Many thanks for the feedback.
