It really looks to me like you are expected to use system calls like chmod(), unlink(), and
nftw() or readdir(). Embedding shell commands does not appear (to me) to be what is expected.
When you delete a directory, you have to delete all the files in the directory first. Then unlink the directory itself. Exactly what
does
open, creat, read, write, lseek and close
Are they all primitive?
:confused:

SADE(8) BSD System Manager's Manual SADE(8)NAME
sade -- sysadmins disk editor
SYNOPSIS
sade
DESCRIPTION
The sade utility is used for various disk administration tasks on FreeBSD systems.
It is generally invoked without arguments for the default behavior, where the main menu is presented.
NOTES
The sade utility aims to provide a handy tool for disk management tasks on an already installed system. The goal is to provide the same text
interface for disk management in bsdinstall(8) in the post-installation environment.
SEE ALSO bsdinstall(8), gpart(8)HISTORY
A program called sade first appeared in FreeBSD 6.3 as a utility encapsulating features from the sysinstall(8) installer. It was replaced in
FreeBSD 10.0 with the equivalent part of bsdinstall(8).
AUTHORS
Nathan Whitehorn <nwhitehorn@FreeBSD.org>
BUGS
The utility misses a lot of nice features, such as tools for manipulating gmirror(8). These will be added later.
