Oh, I didn't know about command -v! And according to http://www.unix.com/man-page/posix/1posix/command/ and http://pubs.opengroup.org/onlinepubs/009696899/utilities/command.html it's a POSIX built-in (not just bash).

I think I will merge #135 and then I will update it to use command -v instead of type.

Thank you!
