I fixed everything you mentioned. I kept basepath because it handles more edge cases. I improved the option parsing to handle --directory dir, although that is neither here nor there (it's GNU.. -ish). The handling is ugly for the sake of POSIX compatibility - if you can think of a more elegant way to write it let me know, I'd be glad to incorporate it. The exit status of type is clearly defined by POSIX (https://pubs.opengroup.org/onlinepubs/9699919799/utilities/t...). Either way, thank you for the exhaustive list of problems, it really helped - please don't hesitate to open issues with any further observations.

more specifically the problem with type is it's not clear whether "An error occurred" includes the case where the command is not found. one could reasonably argue that printing "command not found" is a successful run. additionally, it's only present in the XSI extension. for these reasons, command -v is usually preferred for better POSIX compatibility.
