## What it is
rb is a tiny Ruby script (9 lines) that turns Ruby into an ergonomic command-line text-processing utility, letting you pipe stdin into Ruby one-liners. It supports per-line mode via a -l flag and can be extended with a ~/.rbrc config file.

## Use cases
- process text in shell pipelines with ruby one-liners
- replace awk and sed with ruby
- filter and transform command output line by line
- sort or group lines from stdin
- extract fields from docker ps or df output

## When to choose
- you already know Ruby and want expressive text processing in the terminal
- you find awk/sed syntax awkward for complex transformations
- you want a tiny, dependency-free script instead of a full tool

## When to avoid
- you don't know Ruby
- you need a portable tool on systems without Ruby installed
- you need high-performance processing of very large streams

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: cli, developer-tools, parser
- domain: developer-tools
- platform: cli, ruby
- tags: text-processing, ruby, stdin-pipelines, unix-tools, awk-alternative, command-line, automation, linux, macos
