Re: Command execution

[Chris Siebenmann <cks>]

 Duff's rc lets you define a function that looks like a full path, and
running the full path will run the function (ie, fn /bin/csh ...). I
don't think this is a good idea myself; the uses seem limited to trapping
standard programs when invoked by explicit paths, and I see more problems
as a result than solutions. Contrary to the documentation, Duff's rc
and Byron's behave the *same* for 'foo/bar', and at least Rob Pike a)
thinks this is a good thing and b) uses this feature.
