  rsh works with /bin/sh and ksh. You can either execute the rsh command
(SysV) or execute the shell with the -r flag. You simply set the PATH to
point to a directory containing only the things you want to allow, and
then (assuming a recent shell) set the PATH variable readonly. I usually
create a /usr/rbin directory and link stuff in from /bin and /usr/bin.

Ex:
	PATH=/usr/rbin
	readonly PATH; export PATH
