shellcheck
brew install shellcheck
v0.11.0
GPL-3.0-or-later
Static analysis and linter for bash/sh scripts, written in Haskell.
Why you might care
Catches common shell scripting errors (unquoted variables, missing quotes, logic bugs) before they cause production failures. Fast, single-binary, integrates into CI/CD and editors. No competing tool covers as many shell anti-patterns with as little configuration.
