It runs in a variety of POSIX environments such as Linux, Android, and FreeBSD, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. The authors dubbed it "The Swiss Army knife of Embedded Linux", as the single executable replaces basic functions of more than 300 common commands. It is released as free software under the terms of the GNU General Public License, version 2.

clear is a computer operating system command which is used to bring the command line on top of the computer terminal. It is available in various Unix shells on Unix and Unix-like operating systems as well as on other systems such as KolibriOS.

A console application is a program designed to be used via a text-only computer interface, such as a text terminal, the command line interface of some operating systems or the text-based interface included with most Graphical User Interface (GUI) operating systems, such as the Win32 console in Microsoft Windows, the Terminal in macOS, and xterm in Unix. A user typically interacts with a console application using only a keyboard and display screen, as opposed to GUI applications, which normally require the use of a mouse or other pointing device. Many console applications such as command line interpreters are command line tools, but numerous text-based user interface (TUI) programs also exist.

cowsay is a program that generates ASCII pictures of a cow with a message. It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot. It is written in Perl. There is also a related program called cowthink, with cows with thought bubbles rather than speech bubbles. .cow files for cowsay exist which are able to produce different variants of "cows", with different kinds of "eyes", and so forth. It is sometimes used on IRC, desktop screenshots, and in software documentation. It is more or less a joke within hacker culture, but has been around long enough that its use is rather widespread. In 2007, it was highlighted as a Debian package of the day.

curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications.

In computing, Mosh is a tool used to connect from a client computer to a server over the Internet, to run a remote terminal. Mosh is similar to SSH, with additional features meant to improve usability for mobile users. The major features are:Mosh maintains its session even when "roams", for example by moving to a different Wi-Fi network or when changing from Wi-Fi to 3G. Mosh maintains the terminal session even when a user loses their Internet connection or puts their client to "sleep." In comparison, SSH can lose its connection in such cases because TCP times out. Mosh client attempts to be responsive to keyboard events without waiting for network lag. It uses an adaptive system that predicts whether the application running on the server will decide to echo the user's keystrokes or deletions.

OpenOffice.org (OOo), commonly known as OpenOffice, is a discontinued open-source office suite. It was an open-sourced version of the earlier StarOffice, which Sun Microsystems acquired in 1999 for internal use.

Picospan was a popular computer conferencing tool written by Marcus D. Watts for the Altos 68000.

It was originally written by Ludvig Strigeus. Released under the terms of the GNU General Public License, ScummVM is free software.

In computing, spooling is a specialized form of multi-programming for the purpose of copying data between different devices. In contemporary systems, it is usually used for mediating between a computer application and a slow peripheral, such as a printer. Spooling allows programs to "hand off" work to be done by the peripheral and then proceed to other tasks, or to not begin until input has been transcribed. A dedicated program, the spooler, maintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. Conversely, for slow input peripherals, such as a card reader, a spooler can maintain a sequence of computational jobs waiting for data, starting each job when all of the relevant input is available; see batch processing. The spool itself refers to the sequence of jobs, or the storage area where they are held. In many cases the spooler is able to drive devices at their full rated speed with minimal impact on other processing.

Terminfo is a library and database that enables programs to use display terminals in a device-independent manner.
