I am writing a simple applescript to change the startup disk. but I have one problem...

How can I write the following as one line so that I don't get prompted for a password?


sudo /usr/sbin/nvram boot-device=ide1/@0:5,\\:tbxi


just like you can use username assword@ftp.domain.com to get into a ftp site, is there a way to sudo without getting prompted for a password separately?

From sudo's man page

-S The -S (stdin) option causes sudo to read the password
from standard input instead of the terminal device.

So now all you have to do is have ur applescript write the password u want to stdin after u execute that one line of code. Of course I'm not sure how to do that, but it can't be that hard.

HTH,

Just like this:

echo "thePassword" | sudo -S whoami

Uhm... YUCK YUCK YUCK. Password as plaintext, anybody?

It would be better to create a shell script, and then make that setuid(root). There are directions on how to do this in the archive you can get the search page to work

Well, I am going to compile the script as read only, and it's only on my computer as a shortcut, so it's not a big security issue.

How about for su instead of sudo?


I am using OSX PowerAddOns

As for:

echo "thePassword" | sudo -S whoami

Did anyone get what this is for?

I thought it was what you were asking for. That command will pass thePassword to sudo (As the Password) and then run the command whoami.

So to run your command, you would do:
echo "thePassword" | sudo -S /usr/sbin/nvram boot-device=ide1/@0:5,\\:tbxi

If that doesn't answer the question then I have misunderstood your question.

It does exactly what you want, if you don't want to get into too much detail Essentially this is what unix people call piping, or taking the output of one command and sending it into the input stream of another.

The way to read this (I think) is:
echo "thePassword" -&gt; the command echo takes the argument "thePassword" and just prints it to stdout... except that there's a pipe, so it goes to the input stream of the next command.

| -&gt; let's do the piping

sudo -S whoami -&gt; the sudo command su's (changes users to) the user whoami, whose password is obtained fromt STDIN... but because there was a pipe, that's from the previous command.

I hope that made some sense,
