As it happens, on my platform (z/OS UNIX), the "sh" actually IS a form of korn shell (it was ported to the mainframe by MKS, apparently), so there is a 'whence'. What's weird is that doing something like $path = `whence $cmd | uniq` actually works, though the pipe to uniq is pointless. Something about piping it makes the value come back. Oh well, probably something weird in my UNIX environment. Thanks for the responses.
