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
