Today, terminal-based programs have almost disappeared. GUIs are taking over, whether we like it or not. However, there is still a place for the old command line. Take the internet as an example: everyone’s using Firefox, Thunderbird, and Pidgin for their internet activities. Even though these are great, quality, free software apps, they tend to be bloated. That’s where the terminal comes in.

Introduction

Since most of this article is for the internet, having an internet connection might be useful. Also, you’ll probably need a computer (preferably running GNU/Linux, as many of these programs don’t run on Windows or OS X). Finally, you’ll need a terminal emulator (which most GNU/Linux distributions come with). Windows users have cmd.exe, Mac users have Terminal, GNOME users have gnome-terminal, KDE users mostly use konsole, and Xfce users often use xfce4-terminal. Most operating systems also install xterm or some other terminal program. If your operating system doesn’t have any of these (something I would find hard to believe) there is a list of terminal apps at Wikipedia. And if none of these are installed on your system (something I would find extremely hard to believe), you can always install one using your package manager. As a last resort, try typing Ctrl + Alt + F1 to exit KDE, GNOME, Xfce, or whatever desktop environment you are using (use Alt + F7 to go back).

If you are told to run something in this kind of text, then that means you should copy it into the terminal and hit enter (unless it’s a hotkey like c. In that case, just type c into the terminal and it will run automatically).

Lynx: web browsing from the terminal

Homepage: http://lynx.browser.org/

Back in 1989, a text browser that could browse HTTP and Gopher protocols was born. That browser is still around today. It’s called Lynx. There is absolutely no GUI. All it is is a terminal app with a few different colors. It handles most HTML, supports SSL, and much more. You can even download pictures and movies to view with an external application (like MPlayer). You can use it on servers (which often have no GUI), low resource machines, or just for connecting to the web without all the frills of Firefox. It’s available for Windows, GNU/Linux, and Macintosh (via a fink package or an unofficial build).

wget: Text-based downloader

Sometimes when downloading a file you don’t need all the bloat of a full download manager like KGet. That’s why I like wget, an HTTP(s) and FTP downloader for Windows and GNU/Linux (with an unofficial build for Mac OS X. It supports incomplete downloads, HTTP or FTP mirroring, proxies, and much more. Just type wget [URL], replacing [URL] with the URL of the file, e.g. http://mirror.cc.columbia.edu/pub/linux/ubuntu/releases/kubuntu/feisty/kubuntu-7.04-desktop-i386.iso, and the Kubuntu CD image will start downloading. You can also use wget to mirror sites with the -m flag.

rtorrent: Torrents without a user interface

Sometimes, it’s faster to download a file with the BitTorrent technology than wait for the six thousand other users to leave.
