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?
Hi Ben,
Here is how I do it (this example sets the system clock):
put "#!/bin/sh" & cr into tScript
put "pw=" & quote & tPass & quote & cr after tScript
put "echo $pw | sudo -S date " & tDate & tTime & cr after tScript
-- build the command lines, the command you need to run goes after the -S
put shell(tScript) into tCheck -- do the command & get the result
You have to quote your admin password, but you can ask for that when
running the script, or store it in a custom property.
Thanks Sarah, that's excellent. Completely solves my problem.
Playing around, I note that you can even use your trick as a oneliner, eg
put "echo" && quote & tPass & quote & "| sudo -S" into tSudoPrefix
put shell(tSudoPrefix && tCommand)
with the only apparent difference being that in the full version, the first
line of the result is "Password:", whereas when I do it all one line, that
password prompt doesn't appear. Do you know if the one line version should be
considered less reliable in some way?
Many thanks,
