...huh?  csh sets $path from $PATH on startup, at least in my
experience.  (If you have a .cshrc that overrides the startup path,
that's your lookout.  Also, there's some interesting danger potential
lurking around path elements containing colons, which cannot exist in
$PATH but can in $path.)

But most of the non-csh-family shells have something functionally very
similar to which(1) built in.

After all, if you want which to really tell the truth, it more or less
_has_ to be a builtin.
