Linux Terminal 201: Networking Commands You Should Know! – HakTip 152 from Techmirrors
To run Linux commands, you need to get to the Linux command line prompt.
To get to the Linux command line prompt from a Linux desktop, you open a terminal emulation window.
Linux Tips: You can also go to a virtual terminal and run Linux commands. But when you are a new Linux user, a terminal emulation window is easier to work with.
Linux Terminal Emulation Windows
When you open a terminal emulation window, you get a “window” on the desktop. A terminal emulation window can be moved around on the desktop and resized to be made larger or smaller. And you can even have multiple terminal emulation windows open at the same time!
This window shows the Linux command line prompt, at which you can run Linux commands (by typing in commands and pressing Enter). After running a Linux command, this window also shows the output of the command (very important).
Learn about Linux commands, such as ping, traceroute, and netstat in this episode of HakTip!

Methods of Opening a Linux Terminal Emulation Window (a.k.a. Terminal or Console)
There are over 130 Linux distributions (versions)!
The method of opening a terminal emulation window on your Linux desktop is dependent on the Linux distribution (version) you are using and the Linux desktop you are using. Two popular Linux desktops are the GNOME desktop and the KDE desktop.
To open a terminal emulation window, boot your Linux system to a desktop and then:
- look for an icon on the desktop that looks like a computer screen and click on it
- right-click on the desktop and look for a menu item with the words “Linux terminal”, “Linux console”, or similar
- search the menus on the desktop for the words “Linux terminal”, “Linux console”, or similar, and select the menu item
Linux Concepts and Terms:
A terminal emulation window is also referred to as a “Linux terminal” or “Linux console”.
Linux commands are sometimes referred to as “Linux terminal commands” and “Linux console commands”.
The Linux command line prompt is sometimes referred to as the CLI for “command line interface”.
