terrapin

A language agnostic interactive unix shell.

Features

terrapin is a shell designed for people new to terminal interfaces as well as experienced users who want to remove complexity from their shell environment.

It aims to accomplish the following goals:

• Simple to comprehend and use
• Issue commands without trepidation
• Prevent unintended consequences

These are satisfied through certain design paradigms:

• No builtin scripting language
• Minimal operators
• Aliases and system binaries have different namespaces
• Alias namespace is the default

For more information about how to use terrapin, please consult the documentation.

Installation

terrapin is written in Rust and can be installed with cargo:

bash cargo install terrapin
