Using Linux Commands Rather Than Linux GUI Utility Software Programs
The great thing about learning how to use the Linux commands is that they're actually identical from one version of Linux another!
So, the "real" way to do Linux System Administration is to run Linux commands at the command line prompt, rather than using one of the many slow and cumbersome "point-and-click" GUI ( G raphical U ser I nterface) utilities that only work in the distribution you're currently using – because each distribution has its own particular set of GUI utilities that only work in that single version.
To run a Linux command, you just type in the name of the command, and then type in any other parts of the command, such as the command options, and then press the Enter key.
Typing in a Linux command and then pressing Enter to run it just takes seconds and the command runs instantly – and this is much faster than starting up and using a Linux GUI utility to do the equivalent of running the command.
Running the Linux adduser Command To Create A New Linux User – Example
You can see an example of the Linux command that is used to create a new user named cwest (for Chris West) below.
# adduser -c "Chris West" cwest
The adduser command above is being run "on" the cwest user name to create a user so that this person can log in and do work on a Linux system.
This command creates a new user named cwest with the full name of " Chris West ".
The -c (for comment ) option is used with the Linux adduser command to add the full name of the user to the user name of cwest.
Linux Commands Training Tips: The # (pound symbol) on the example above represents the command line prompt.
Keep this in mind, you do not type in the prompt, you just type in the Linux command that appears at the right of the prompt.
The command prompt may also appear as: $ (a dollar sign) or appear with another symbol, instead of # (pound or number) symbol or $ (dollar sign) symbol.
