When working on a Linux desktop as an "ordinary" Linux users, often at the command prompt, you must go and lead System Administration Commands.

And perform many of these commands, you need root user name (also known as the superuser to work).

Linux Commands Training Tips: The super user name is abbreviated below (and you'll see) how to use the command with the same name below.

To use the Linux su command (with -) forwork request to change from working as a "normal" users as root.

A "normal" user, root is also known as "unnamed" user.

For security reasons, you should never register to root a Linux desktop with the username. So you need to be "normal" user and then be on the desktop and open the steps to "a Linux" terminal emulation window to prompt the command line.

At the command prompt as "normal" user, you must run the Linux su command to"Login" and change the work as "non-root" to work as root, so you can run the powerful Linux system administration commands.

With the Linux su command as root super-user work

When using Red Hat, Fedora, SuSE, Debian and many other distributions after you log in to a Linux desktop as a "normal" and "non-root" and opening a terminal emulation window, the prompt appears as $ (a dollar sign icon).

At this pointThey do not work as the root user.

Here's how to run the Linux su command:

All of the following examples try to gain real, practical experience training commands.

$ Su —

Be sure to use the – (minus) as on the right side of the above command. Thus, the "root-user environment.

After running the command above to the command prompt, from $ (a dollar sign) to show # (a number, character) that you're working, "asRoot user "and not" as a normal user.

Now you can load Linux system administration commands.

To back "lead to working as a" normal "users, the exit command Linux:

$ Exit

Linux Commands Training Tips: If you are running the commands, then with them "in the Bash Shell") (environment and if you use the su command) (with a hyphen option to work as root, you are actually opening a " subshell "in the" bashShell.

When you run the exit command, you are "Exit" from the bottom shell (as root) to the "normal" shell!

Debian Linux is a "major" Linux distribution, and the following distributions "on" or "derived from" this version – and as the examples above will work on the following distributions as well:

Ubuntu, Damn Small Linux, Dream Linux, Kanotix, Knoppix, LinEx, Linspire, MEPIS, sidux, Xandros – and much more!
