The Linux Command Line by William Shotts is a 596-page book for new command line users covering command line use, shell scripting and common command line programs. Released under a BY-NC-ND Creative Commons license, it is available as a free PDF download. A sequel, Adventures with the Linux Command Line, is also available as a free PDF download.
fish is a command line shell for Linux, macOS, BSD and Windows, described as friendly and interactive. It offers syntax highlighting, autosuggestions and tab completion with selection lists. Documentation states it is designed to be ready to use without extensive configuration, and its scripting syntax is presented as easy to learn and use.
A shell history tool that syncs, searches and backs up shell history with end-to-end encryption, available for macOS, Linux and Windows and for shells including bash, zsh and fish. It includes Atuin AI, which is free during testing and can suggest and run commands.
Eat is an Emacs terminal emulator that runs full-screen terminal programs, including Emacs itself. It is implemented entirely in Emacs Lisp and is described as more than three times faster than Term. It offers Sixel support, complete mouse support and shell integration, and can be started with M-x eat.
Dino is an open-source chat client for the desktop built on the XMPP protocol. It offers a clean interface with encryption; end-to-end encryption via OMEMO or OpenPGP can be enabled, and read and typing notifications can be disabled. Dino is developed on GitHub by an open community and is available from repositories of many Linux distributions.
Photon is an RSS/Atom reader focused on speed and usability, designed as a terminal-based viewer with image support via sixel. It is extensible with Lua plugins and can use OpenCL for image scaling. Photon does not include features for adding or managing feeds; feed URLs are supplied via command-line arguments, text files, or external commands.
Oils is a project offering OSH, which runs existing shell scripts, and YSH, intended for Python and JavaScript users who avoid shell. Both live inside the same 2 MB oils-for-unix binary. Published documentation includes a getting-started guide, a YSH tour, an Oils reference, and comparisons of YSH with shell idioms.
