using sudo in shell?

[Ben Rubinstein]

The 'shell' command is a very useful extension to Rev's native powers. 
However, there are some things, at least on OS X, which I want to do that 
require the shell command to be issued in super-user mode.

Is there any way to make this happen?   If you are working in the terminal, 
you can issue the command as "sudo <x>" and you will be asked for the 
password.  Prefix your parameter to "shell" with "sudo", and the result will 
be the single line prompt "Password:".

I don't even know if this is a Rev question, or a bash question, or an OS X 
question.  But does anybody know of a way that one can in effect pass a 
password to shell in this situation, or in any other way get round this problem?

TIA,
