Xonsh is a Python-ish, BASHwards-looking shell language and command prompt. The language is a superset of Python 3.4+ with additional shell primitives that you are used to from Bash and IPython. It works on all major systems including Linux, Mac OSX, and Windows. Xonsh is meant for the daily use of experts and novices alike.

GNU Rush is a restricted user shell, for systems on which users are to be provided with only limited functionality or resources. Administrators set user rights via a configuration file which can be used to limit, for example, the commands that can be executed, CPU time, or virtual memory usage.

Es is an extensible shell. The language was derived from the Plan 9 shell, rc, and was influenced by functional programming languages, such as Scheme, and the Tcl embeddable programming language. This implementation is derived from Byron Rakitzis's public domain implementation of rc, and was written by Paul Haahr and Byron Rakitzis.

Linenoise is a minimal, zero-config, readline replacement. Its features include:

1. Single and multi line editing mode with the usual key bindings

2. History handling

3. Completion

4. Hints (suggestions at the right of the prompt as you type)

5. A subset of VT100 escapes, ANSI.SYS compatible

Oils is a programming language with automatic translation for Bash. It includes OSH, a Unix/POSIX shell that runs unmodified Bash scripts and YSH is a legacy-free shell, with structured data for Python and JavaScript users who avoid shell.

This is a reimplementation by Byron Rakitzis of the Plan 9 shell. It has a small feature set similar to a traditional Bourne shell.

Dash is a POSIX-compliant /bin/sh implementation that aims to be as small as possible, often without sacrificing speed. It is faster than the GNU Bourne-Again Shell (bash) at most scripted tasks. Dash is a direct descendant of NetBSD's Almquist Shell (ash).

Fish (friendly interactive shell) is a shell focused on interactive use, discoverability, and friendliness. Fish has very user-friendly and powerful tab-completion, including descriptions of every completion, completion of strings with wildcards, and many completions for specific commands. It also has extensive and discoverable help. A special help command gives access to all the fish documentation in your web browser. Other features include smart terminal handling based on terminfo, an easy to search history, and syntax highlighting.

The Z shell (zsh) is a Unix shell that can be used as an interactive login shell and as a powerful command interpreter for shell scripting. Zsh can be thought of as an extended Bourne shell with a large number of improvements, including some features of bash, ksh, and tcsh.

Tcsh is an enhanced, but completely compatible version of the Berkeley UNIX C shell (csh). It is a command language interpreter usable both as an interactive login shell and a shell script command processor. It includes a command-line editor, programmable word completion, spelling correction, a history mechanism, job control and a C-like syntax.

Scsh is a Unix shell embedded in Scheme. Scsh has two main components: a process notation for running programs and setting up pipelines and redirections, and a complete syscall library for low-level access to the operating system.

Gash is a POSIX-compatible shell written in Guile Scheme. It provides both the shell interface, as well as a Guile library for parsing shell scripts. Gash is designed to bootstrap Bash as part of the Guix bootstrap process.

loksh is a Linux port of OpenBSD's ksh. It is a small, interactive POSIX shell targeted at resource-constrained systems.

Gash-Utils provides Scheme implementations of many common POSIX utilities (there are about 40 of them, ranging in complexity from false to awk). The utilities are designed to be capable of bootstrapping their standard GNU counterparts. Underpinning these utilities are many Scheme interfaces for manipulating files and text.

pay-respects provides a shell helper to suggest correction for mistyped commands, with guix locate integration and an alias (default to f) to correct the previous command.

This package provides an interactive setup for zsh preconfigured by the Grml project.

grc can be used to colourise logfiles, output of shell commands, arbitrary text, etc. Many shell commands are supported out of the box.

You might want to add these lines you your ~/.bashrc:

GRC_ALIASES=true
source $GUIX_ENVIRONMENT:-$HOME/.guix-profile/etc/profile.d/grc.sh

The ascii utility provides easy conversion between various byte representations and the American Standard Code for Information Interchange (ASCII) character table. It knows about a wide variety of hex, binary, octal, Teletype mnemonic, ISO/ECMA code point, slang names, XML entity names, and other representations. Given any one on the command line, it will try to display all others. Called with no arguments it displays a handy small ASCII chart.

Starship is a shell prompt that is fast and configurable, and works on most common shells. It shows information from various sources in a way easy to grasp at a glance, including but not limited to: the hostname/username/cwd trio, git, project language and runtime.

Note: Users must have a nerd font installed and enabled in their terminal.

RIG (Random Identity Generator) generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to cross-check the city, state, zip, or area code, it will check out.

conflict examines the user-specifiable list of programs, looking for instances in the user's path which conflict (i.e., the name appears in more than one point in the path).

direnv can hook into the bash, zsh, tcsh, and fish shells to load or unload environment variables depending on the current directory. This allows project-specific environment variables without using ~/.profile.

Before each prompt, direnv checks for the existence of a .envrc file in the current and parent directories. This file is then used to alter the environment variables of the current shell.

The file renaming utilities (renameutils for short) are a set of programs designed to make renaming of files faster and less cumbersome. The file renaming utilities consists of five programs: qmv, qcp, imv, icp, and deurlname.

Liquidprompt is an adaptive prompt for Bash and Zsh that gives you a nicely displayed prompt with useful information when you need it. It does this with a powerful theming engine and a large array of data sources.

In order to use liquidprompt with Zsh, you should use the following snippet with Guix Home:

(service home-zsh-service-type
         (home-zsh-configuration
           (zshrc (list ;;...
                    ;; This loads liquidprompt
                    (mixed-text-file "liquidprompt"
                                     "[[ $- = *i* ]] && source " liquidprompt "/share/liquidprompt/liquidprompt")
                    ;; This loads the powerline theme available in liquidprompt
                    (mixed-text-file "powerline-theme"
                                     "source " liquidprompt "/share/liquidprompt/themes/powerline/powerline.theme"))))))
