bash-shortening

What problem does it solve?

This skill helps you refactor overly long or repetitive Bash scripts into more idiomatic, readable code while avoiding risky “golf” rewrites that hurt maintainability.

Core Features & Use Cases

• Rewrite verbose Bash to idiomatic constructs: shortens common patterns using Bash features like parameter expansion, brace expansion, process substitution, and arithmetic contexts.
• Guided, safe refactoring workflow: runs a read-only analyzer sweep over reference categories, then applies deterministic rewrites from a rewriter, and finally verifies output.
• Respects portability and safety constraints: refuses to operate on non-bash shells or POSIX /bin/sh scripts where Bashisms would break, and avoids cryptic one-liners when readability would suffer.

Quick Start

Use the skill on a Bash script file path by running python3 scripts/bash-shorten.py --apply path/to/script.sh.
