Hi:

Have a look at the 'sh-posix(1)' manpages under the section titled "rsh Restrictions".

Regards!

Hi (again):

Hmmm, so what wasn't useful in the answer I provided?

The restricted shell environment presumes that the commands you want a user to be able to execute are available in his/her PATH. In particular, a user cannot specify a command with '/' at its beginning, 'cd' to a directory; nor can they set their PATH variable.

As for seeing that a user has the permission to execute a paricular command, that is governed by the ownership and permissions of the executable and by the ability of the user to search the directory containing the command!

I agree with James about the use of Restricted Shell. Also, if you check this link:

You can see that points from:

1-3: The answer didn't really help answer my question, but thanks for your assistance!

At least thanks for the answer. Would be nice if you don't assign 0 points to the answers even if you consider that is not usefull, just to thank the effort.
