executed had these names been given as commands.

PATH
.
If the
-a
flag is given,
which
will continue to search the
PATH
until all instances of a program file are found.

which
command appeared in
3.0BSD.
BUGS
This implementation does not expand
csh(1)
aliases, and is shell agnostic.
This is really a feature.
