Intro

There are over 130 Linux distributions (versions) and they can be administered (managed) by Linux Graphical User Interface (GUI) utilities – or by using Linux commands. Linux GUI utilities give you a “point-and-click” interface for doing Linux administration tasks, like working with the Linux file system (to make directories and copy files), and to create Linux users. However, they are slow and awkward to use – and even worse, they are different from one Linux distribution to another!On the flip side, Linux commands are virtually identical from one Linux distribution to another. So, when you learn a Linux command in one Linux distro, that same command will work in all 130+ Linux distros.

Linux is actually Not Difficult

However, new Linux users often have difficulty learning how to use Linux commands to administer the Linux OS (operating system). This is because most Linux training materials are poorly written by Linux techies that don’t know how to write in plain English for people new to Linux.

TIPS

When you get Linux training, don’t spend time learning Linux GUI utilities – learn how to use Linux commands, even though they are a bit harder to learn than GUI utilities.

  • Linux Command NamesLinux command names are often an abbreviation of what the command does. For example, the rm command stands for remove.
  • Linux command names and command options are “case sensitive”. Lower case letters need to be typed in lower case and vice versa. You must type in a Linux command and the options of the command, exactly as shown.
  • Be sure to put a space between the Linux command name, its options, and what the Linux command is being run “on”, such as the name of a file.
