In general, you would want to set up a restricted user, perhaps using the
computer to operate automated equiptment. (Though I can't justify the
need for a shell rather than a well written control program.)
You would set up a sub-structure complete with a home directory and a
home/bin directory. The user would (obviously) be placed in the home
directory upon login, the PATH set to home/bin. (S)he could then use
the commands/programs inside the home/bin directory, yet would not be able
to change directory (to poke around the system, etc.) or use commands
not authorized.

These are my opinions and you can't have them.
