Vim is a free and open-source, screen-based text editor program. It is an improved clone of Bill Joy's vi. Vim's author, Bram Moolenaar, derived Vim from a port of the Stevie editor for Amiga and released a version to the public in 1991. Vim is designed for use both from a command-line interface and as a standalone application in a graphical user interface. Since its release for the Amiga, cross-platform development has made it available on many other systems. In 2018, it was voted the most popular editor amongst Linux Journal readers; in 2015 the Stack Overflow developer survey found it to be the third most popular text editor, and in 2019 the fifth most popular development environment.
Xfce or XFCE is a free and open-source desktop environment for Linux and other Unix-like operating systems.
A man page is a form of software documentation found on Unix and Unix-like operating systems. Topics covered include programs, system libraries, system calls, and sometimes local system details. The local host administrators can create and install manual pages associated with the specific host. A manual end user may invoke a documentation page by issuing the man command followed by the specific detail they require. These manual pages are typically requested by end users, programmers and administrators doing real time work but can also be formatted for printing.
The Oberon System is a modular, single-user, single-process, multitasking operating system written in the programming language Oberon. It was originally developed in the late 1980s at ETH Zurich. The Oberon System has an unconventional visual text user interface (TUI) instead of a conventional command-line interface (CLI) or graphical user interface (GUI). This TUI was very innovative in its time and influenced the design of the Acme text editor for the Plan 9 from Bell Labs operating system.
curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications.
In computing, text-based user interfaces (TUI), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator.
Far Manager is an orthodox file manager for Microsoft Windows and is a clone of Norton Commander. Far Manager uses the Win32 console and has a keyboard-oriented user interface.
sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. It originally stood for "superuser do", as that was all it did, and this remains its most common usage; however, the official Sudo project page lists it as "su 'do'". The current Linux manual pages for su define it as "substitute user", making the correct meaning of sudo "substitute user, do", because sudo can run a command as other users as well.
GNOME Terminal is a terminal emulator for the GNOME desktop environment written by Havoc Pennington and others. Terminal emulators allow users to access a UNIX shell while remaining on their graphical desktop.
GNU Oleo is a discontinued lightweight free software spreadsheet originally designed as a text-based spreadsheet using the curses library. The last development version of Oleo, 1.99.16, was released in 2001.
Uzbl is a discontinued free and open-source minimalist web browser designed for simplicity and adherence to the Unix philosophy. Development began in early 2009 and is still considered in alpha software by the developers. The core component of Uzbl is written in C, but other languages are also used, most notably Python. All parts of the Uzbl project are released as free software under GNU GPL-3.0-only.
i3 is a tiling window manager designed for X11, inspired by wmii and written in C. It supports tiling, stacking, and tabbing layouts, which are handled manually. Its configuration is achieved via a plain text file and extending i3 is possible using its Unix domain socket and JSON based IPC interface from many programming languages.
Redshift is an application that adjusts the computer display's color temperature based upon the time of day. The program is free software and is intended to reduce eye strain, as well as insomnia.
cat is a standard Unix utility that reads files sequentially, writing them to standard output. The name is derived from its function to (con)catenate files . It has been ported to a number of operating systems.
mpv is free and open-source media player software based on MPlayer, mplayer2 and FFmpeg. It runs on several operating systems, including Unix-like operating systems and Microsoft Windows, along with having an Android port called mpv-android. It is cross-platform, running on ARM, MIPS, PowerPC, RISC-V, s390x, x86/IA-32, x86-64, and some other by 3rd party.
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to also work for Internet of Things devices and desktop applications.
Redox is a Unix-like operating system for x86 computers, based on a microkernel design. It is community-developed, released as free and open-source software and distributed under an MIT License. Written in the programming language Rust, Redox aims to be a general-purpose operating system that is safe and reliable. It is currently in a pre-stable status.
Windows Subsystem for Linux (WSL) is a feature of Microsoft Windows that allows for using a Linux environment without the need for a separate virtual machine or dual booting. WSL is installed by default in Windows 11. In Windows 10, it can be installed either by joining the Windows Insider program or manually via Microsoft Store or Winget.
Foliate is a free and open-source program for reading e-books in Linux. In English, foliate is an adjective meaning to be shaped like a leaf, from the Latin foliatus, meaning leafy.
Qalculate! is an arbitrary precision cross-platform software calculator. It supports complex mathematical operations and concepts such as derivation, integration, data plotting, and unit conversion. It is a free and open-source software released under GPL v2.
