Unless you want to use rm(1)'s "-r" option.  Consider:

    $ cd /tmp/example
    $ mkdir -p a/b/c/d
    $ ls *
    b
    $ rm *
    rm: a: is a directory
    $ ls -r *
    b
    $ rm -r *
    $ ls
    $ mkdir -p a/b/c/d
    $ ls -R *
    b

    a/b:
    c

    a/b/c:
    d

    a/b/c/d:
    $ rm -r *
    $

The real truth is that there are invocations of rm(1) that will
have results that cannot be predicted by simple use of other
standard tools, although find(1) can be used to assist with the
impact of rm(1)'s "-r" option.

I once added a "-n" option to rm(1) that worked the same way as
the similarly named option in make(1); some of my customers said
it was helpful. 

Cheers, Greg
