Minimal Linux Live is a tiny educational Linux distribution, which is designed to be built from scratch by using a collection of automated shell scripts. Minimal Linux Live offers a core environment with just the Linux kernel, GNU C library and Busybox userland utilities. Additional software can be included in the ISO image at build time by using a well-documented configuration file. Minimal Linux Live can be downloaded as a pre-built image, built from scratch or run in a web browser by using a JavaScript PC emulator.

Avoid switching between Clojure and bash scripts. Enjoy your parens on the command line. Leveraging GraalVM native-image and the Small Clojure Interpreter, babashka is a self-contained and instantly starting scripting environment. Babashka comes with scripting batteries included: tools.cli, cheshire, babashka.fs, babashka.process, java.time and many more libraries and classes. Babashka scripts work on linux, macOS and Windows. Besides the built-in libraries, babashka is able to load libraries from source, tapping into the world of already existing Clojure libraries. Babashka supports real JVM threads and like Clojure, supports futures and dynamic thread-locally bound vars. Babashka features a built-in task runner which covers the most popular use cases of make, just and npm scripts. Babashka can shell out to other CLI programs like you are used to in bash. It goes one step further and offers seamless integration with other binaries using the pod protocol.

Finally, a command line shell for the 90s. fish is a smart and user-friendly command line shell for Linux, macOS, and the rest of the family. fish suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0! fish supports 24 bit true color, the state of the art in terminal technology. Behold the monospaced rainbow. fish is fully scriptable, and its syntax is simple, clean, and consistent. You'll never write esac again. For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page. Other shells support programmable completions, but only fish generates them automatically by parsing your installed man pages. fish will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.

INim is an interactive shell (REPL) for the Nim programming language, providing a platform for executing Nim code snippets in real-time.

SoupToNuts is a repository of technical articles and example software covering Postfix, OpenSSH, C and C++, Live Linux CD, MySQL, SQLite, Berkeley DB, Bash and System Administration.

bash-completion is a collection of command-line command completions for the Bash shell, a collection of helper functions to assist in creating new completions, and a set of facilities for loading completions automatically on-demand, as well as installing them. The easiest way to install this software is to use a package; refer to Repology for a comprehensive list of operating system distributions, package names, and available versions. Depending on the package, you may still need to source it from either /etc/bashrc or ~/.bashrc (or any other file sourcing those). If you don't have the package readily available for your distribution, or you simply don't want to use one, you can install bash-completion using the standard commands for GNU Autotools packages. If you find that a given function is producing errors or does not work as it should under certain circumstances when you attempt completion, try running set -x or set -v prior to attempting the completion again.

pipestatus - source file for UNIX/POSIX shell that allows to obtain an exit status of every program in a pipe.

Mainly this project aims at easing startup and use of XCSoar (see xcsoar.org) on Kobo Mini. But the scope of use should not be limited solely to XCSoar. The Launcher should be small in code size, reuse most of the original libraries, provide flexible configuration to any application that might be ported to the Kobo Mini. It supports customizable fonts, toolbox-pages, buttons (also graphical), labels, autostart and sleep timers.

Viewglob is a tool to increase the usability of the Unix shell in graphical environments. It watches your shell activity in an xterm and tracks file selections and potential name completions in a GTK+ display showing the layouts of relevant directories.

Jail Chroot Project is an attempt of write a tool that builds a chrooted environment. The main goal of Jail is to be as simple as possible, and highly portable. The most difficult step when building a chrooted environment is to set up the right libraries

Yum Repo Sync is a shell script that synchronizes a local directory with a repository mirror using rsync. Yum Repo Sync provides one easy way to create and maintain a local repository to YUM.

This is a small Shell-Script that Updates Programs for Linux. It will only work on Systems that support 'apt-get'. Source-Code is provided as a .txt file, and a .sh file. (The 'Source' .sh file lets you keep your Version and the original separate).

Bash Navigator eliminates the requirement that users must memorize long directory names, provides forward/back/next/previous navigation keys, and supports a rudimentary form of project management without reducing the flexibility of the BASH shell.

BatchLogin is a shell connection virtualization program. It allows a user on a complex network to connect and execute scripts and commands upon groups of machines without having to deal with the connection specifics every time.

env-switcher effectively allows users to manipulate the environment loaded for all shells (including non-interactive remote shells) without manually editing their startup dot files -- something that users traditionally have difficultly doing properly.

Sakura is a Knowledge Navigator and User Interface for UNIX, which implements HyperMedia and its own windowing and packing system, both in the main program and in an extensive API for Tcl and other languages.

A simple shell script that will help you keep track of all your SSH connections.

Shell.NET is a set of console and winform applications written in C#. It features nearly 100 applications ranging from classical Unix applications like basename, cal, grep, tr, uniq, and wc, to some very unique tools like RunScript or TextTransform.
