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.

    Extreme Ultimate .bashrc

    Extreme Ultimate .bashrc

    Extreme ultimate .bashrc configuration file for Bash

    Do you want a more robust experience from your bash shell? As a Linux systems administrator, I've been working on this .bashrc file for well over a decade. Over the years, I have searched through scores of others' .bashrc and script files collecting and improving on new ideas and features. This portable drop in bash configuration file can be used on any system anywhere you use a terminal. It will detect most settings on most systems and make sure your environment has every feature available automatically without any additional effort. Do you need a command line cheat sheet? Press CTRL-h for full color help! I think this is the most amazing, ultimate .bashrc file I have ever seen and wanted to share it. To install, execute the following lines in a terminal wget -O ~/.bashrc https://sourceforge.net/projects/ultimate-bashrc/files/_bashrc/download wget -O ~/.bashrc_help https://sourceforge.net/projects/ultimate-bashrc/files/_bashrc_help/download

    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.

    kube-ps1

    kube-ps1

    Kubernetes prompt info for bash and zsh

    A script that lets you add the current Kubernetes context and namespace configured on kubectl to your Bash/Zsh prompt strings (i.e. the $PS1). The default prompt assumes you have the kubectl command-line utility installed. Official installation instructions and binaries are available. Blue was used for the default symbol to match the Kubernetes color as closely as possible. Red was chosen as the context name to stand out, and cyan for the namespace. 256 colors are available by specifying the numerical value as the variable argument. Due to the vast ways of customizing the shell, please try the prompt with a minimal configuration before submitting a bug report.
