An A-Z index of the Linux command line, covering bash and related utilities. The page alphabetically lists commands with short descriptions, such as alias for creating aliases, apt for installing software packages, and chmod for changing access permissions.
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.
The FreeBSD Wiki is a MoinMoin-powered community wiki for the FreeBSD project. It hosts pages on contributing to FreeBSD, community channels, supported hardware and platforms, development tools, active and inactive projects, the base system, ports and packages, and documentation. It also includes an introduction to the wiki, account creation and editing guidelines.
Actions is a utility that adds additional actions to the Shortcuts app. The source states it adds 180+ free actions on macOS, iOS, and visionOS and that they do what the built-in actions cannot. It is described as free and available on macOS, iOS, and visionOS.
SongRec is an unofficial open-source Shazam client for Linux written in Rust. It recognizes audio from an arbitrary audio file or from the microphone, usable through both a GUI and a command line. The GUI provides a history of recognized songs exportable to CSV, and the tool can continuously detect songs from the microphone with a selectable input device.
greetd is a minimal and flexible login manager daemon that makes no assumptions about what to launch. It can start anything runnable from a shell in a TTY, and programs that speak a simple JSON-based IPC protocol can act as greeters. The project provides agreety, a simple text-based greeter, and lists third-party greeters for graphical and console sessions.
Heads is an open source custom firmware and OS configuration for laptops and servers. It combines physical hardening of hardware platforms and flash security features with custom coreboot firmware and a Linux boot loader in ROM, measuring boot steps into the TPM. It is intended for cases where data and state are stored on the computer.
