We are designing a system and want to give the (ab)users the capability
of using the shell for certain tasks (e.g. editing personal files, reading
mail, etc.). The problem is that the users have to have access to certain
system files through the application but we don't want them modifying those
files arbitrarily using the shell. We have a command called rsh (restricted
shell) which restricts "cd", environment variables, and some other things,
but doesn't place any restrictions on command arguments (so "vi /etc/passwd"
works). What we are actually looking for is being able to let the users
do anything they want within their "home tree", so that they can create
and change directories, files, etc. in their own area, but can't go higher
than their home directory. We are anticipating having to write a special
shell for our system and are basically looking for a starting place rather
than starting from scratch. Does anyone have any PD stuff out there that
with a little modification would provide the capabilities we need?
