newsboat is an open-source RSS/Atom feed reader for text terminals. It runs
on Linux, FreeBSD, Mac OS X and other Unix-like operating systems.
newsboat's configurability and vast number of features make it a
perfect choice for people that need a slick and fast feed reader that can
be completely controlled via keyboard.

DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible without sacrificing speed where possible.

This is not the original rc shell by Tom Duff.

It is a re-implementation of it by Byron Ratikiz and community.

cpulimit is a simple program that attempts to limit the CPU usage
of a process (expressed in percentage, not in CPU time). This is
useful to control batch jobs when you don't want they eat too
much CPU. It does not act on the nice value or other scheduling
priority details, but on the real CPU usage. Also, it is able to
adapt itself to the overall system load, dynamically and quickly.

While fd does not seek to mirror all of find's powerful functionality,
it provides opinionated defaults for 80% of the use cases.

fzf is an interactive Unix filter for the CLI for any list; files, command history, processes, hostnames, bookmarks, git commits, etc.

hungrycat is a tool that prints the contents of a file on the standard output
while simultaneously freeing disk space occupied by the file. It can be useful
if you need to process a large file, but you don't have enough space to store
the output file, and you won't need the input file afterward.

This tool can be described as a Tiny Dirty Linux Only* C command that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip, cat, ...) currently running on your system and displays the percentage of copied data.

It can now also display an estimated throughput (using -w flag).

ripgrep is a cross-platform, line-oriented search tool that recursively searches your current directory for a regex pattern while respecting your gitignore rules.

ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.

PCem (short for PC Emulator) works with software designed for IBM PC compatibles.

Originally developed as an IBM PC XT emulator, it later emulates other IBM PC compatible computers as well.

Compton is a compositor for X, and a fork of xcompmgr-dana (in turn, a fork of xcompmgr)

Bugs were fixed, and some features added.

Fixes from the original xcompmgr:
* fixed a segfault when opening certain window types
* fixed a memory leak caused by not freeing up shadows (from the freedesktop repo)

Changes from xcompmgr:
* inactive window transparency (specified with -i)
* titlebar/frame transparency (specified with -e)
* menu transparency
* shadows are now enabled for argb windows, e.g. terminals with transparency
* removed serverside shadows (and simple compositing) to clean the code, the only option that remains is clientside shadows

The above features give compton a feature set similar to the xfce compositor.

Compton's frame transparency should work with any window manager that properly sets _NET_FRAME_EXTENTS.

Alacritty is a cross platform terminal emulator written in Rust that uses the GPU for rendering.

Features
* GPU rendering
* Unicode support
* Compiled-in powerline font
* Compatible with monospaced TTF/OTF fonts
* Font ligatures
* Themes
* Hints: Context-aware overlays (e.g. hex color viewer,
octal permission annotation)
* Take screenshots with a single key-binding
* Sixels
* Window transparency (0-100%)
* Customizable cursor (most popular image formats supported)

Simple X11 terminal from the "suckless" project.

termit is a terminal emulator based on the vte library.

It includes tabs, bookmarks, and the ability to switch encodings.

It is extensible via Lua.

xiate uses VTE as the backend. It targets users who run window managers.

Users who want to change settings need to recompile “config.h”.

feh is a versatile and fast image viewer using imlib2, the
premier image file handling library. feh has many features,
from simple single file viewing, to multiple file modes using
a slideshow or multiple windows. feh supports the creation of
montages as index prints with many user-configurable options.

A program to capture screenshots. Features:

* Customizable appearance
* Annotation and drawing tools
* DBus interface
* Export to file, web

A tiling window manager based on binary space partitioning.
* It only responds to X events, and the messages it receives on a dedicated socket.
* bspc is a program that writes messages on bspwm's socket.
* bspwm doesn't handle any keyboard or pointer inputs: a third party program (e.g. sxhkd) is needed in order to translate keyboard and pointer events to bspc invocations.

bumblebee-status is a modular, theme-able status line generator for the i3 window manager

ctwm is Claude Lecommandeur's extension to twm; in addition to the features of twm, it supports multiple virtual screens, the pixmap file format, pinnable ("sticky") menus, and other enhancements.

Echinus is a lightweight window manager for X based on dwm's source code. It
manages windows in tiled, maximized, and floating layouts. It is extremely
small, rather fast, and supports Xft. It features nice titlebars, multiple
desktops, theming support, a simple configuration file, the ability to switch
desktops with the mouse wheel, X bitmaps for title buttons, and true
transparency support (through xcompmgr). There is no need to recompile or
restart X to change its configuration.

euclid-wm is a minimalist tiling window manager for X11. It is designed to
allow quick and easy management of numerous windows entirely from
easy-to-learn, Vim-like key-bindings. It seeks to do two things in particular:
balance the ease of use common among automatic-layout tiling window managers
with the flexibility of manual layout window managers, and create a useful way
to handle minimized applications.

i3 is a tiling window manager.

fork of i3, a tiling window manager. gaps merged upstream since 4.22
