Shellcheck is great, but requires some investment to tailor to your style Disable default checks or enable optional ones using directives: https://www.shellcheck.net/wiki/Directive https://www.shellcheck.net/wiki/Directive The error checks can be pretty arcane: https://github.com/koalaman/shellcheck/wiki/Checks https://github.com/koalaman/shellcheck/wiki/Checks I appreciate that the text for each check is brief and usually includes a suggestion. I end up disabling 26xx's a lot (for unquoted variables to be interpreted as multiple values). Python is probably the best alternative to bash, but Swift is getting surprisingly good. With shwift[1] you get NIO/async APIs, operator overloading for shell-like locutions, and trivial access to existing executables: /// Piping between two executables try await echo("Foo", "Bar") | sed("s/Bar/Baz/") /// Piping to a builtin try await echo("Foo", "Bar") | map { $0.replacingOccurrences(of: "Bar", with: "Baz") } Scripts can easily be configured with libraries and run pre-compiled by using clutch[2]. For cross-platform use, be sure only use libraries on all platforms (i.e., not Foundation). It's a pain, but at least the error shows up typically at compile-time instead of run-time.
