    fish

    fish

    The user-friendly command line shell

    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.

    Babashka

    Babashka

    Native, fast starting Clojure interpreter for scripting

    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.

    bash-completion

    bash-completion

    Programmable completion functions for bash

    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.

    System_42

    Ultra-Lightweight Superior Calibre Linux Distro

    An excellent system-development distribution. Comes with kernel, libc, cc, and emacs. Also contains theTool, and rc. Roll-your-own distro, bring tarballs. Unpack a bootable sample fs, and then unpack libc, tools, and c-compiler then use theTool to build Perl -> autoconf, etc., gmp, mpfr, etc, then g++ and gdb, linux-7. See the shell programs and filesystem in the 'Files' section. Also see the /.bash_history file. Be sure to post in the forum/discussion 'kconfig' because there are a few caveats to "boot and build". Thanks, Dru
