After seeing Bourne shell and C language versions of a program
to create sub-sub-sub directories, it seemed to me that the Cshell
offered the simplest quick implementation, one that only creates
ONE subprocess. It suffices to let mkdir produce all diagnostics.
Voila elegance -

#! /bin/csh -f
# invokes mkdir with all extra args prerequisite to creating the desired d's
set mkarg = ()
while ( $#argv > 0 )
    set path = ("$1")
    set d = "$1:h"
    while ( "$d"X != X && "$d" != "$path[1]" && ! -e "$d" )
	set path = ("$d" $path:q)
	set d = "$d:h"
    end
    set mkarg = ($mkarg:q $path:q)
    shift
end
/bin/mkdir $mkarg:q
# end
