## What it is
Closh is a bash-like interactive shell built on Clojure and ClojureScript, letting users mix traditional unix shell commands with Clojure code for data manipulation. It is an experimental proof-of-concept that has been on hiatus since 2022.

## Use cases
- replace bash with a lisp-based shell
- pipe shell command output into Clojure data transformations
- write shell scripts in Clojure instead of bash
- experiment with modern shell design ideas
- manipulate structured data in the shell instead of text

## When to choose
- you know Clojure and want shell scripting in a familiar language
- you want to explore or hack on an experimental lisp shell
- you prefer Clojure's data manipulation functions over arcane bash syntax

## When to avoid
- you need a reliable daily-driver shell - the project is on hiatus and recommends fish instead
- you need robust scripting - use babashka as the author suggests
- you need production stability or active maintenance

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: cli, interpreter, developer-tools
- domain: developer-tools, programming-languages
- platform: cli
- tags: shell, clojure, clojurescript, bash-alternative, lisp-shell, on-hiatus, command-line, linux, macos
