概要
Rash is a powerful bidirectional shell safety tool designed to solve the inherent difficulties of writing safe and reliable shell scripts. It allows developers to write shell scripts in Rust, which are then transpiled into deterministic, POSIX-compliant shell code with automatic safety guarantees, preventing common issues like shell injection and word splitting. Alternatively, Rash can purify existing legacy bash scripts, automatically transforming unsafe patterns into secure, idempotent, and deterministic equivalents, ensuring consistent and reproducible execution across any POSIX-compliant system without runtime dependencies.
