said by File Quit:Hey,
Sadly, some of our older applications do not play nicely with Classic in X. So instead of us, the admins, having to log out of the student account(which sometimes goes into a blue screen to black and white Darwin prompt), log into the admin account, and change the startup disk, is there an AppleScript we can make for the student account to have the ability to restart in OS 9? Thanks!!!

Seems impossible without using a shell script, but I posted over at Macscripter.net in the Applescript-OS X forum to see if they can help out. There is also the issue with storing the admin password in the script.....

we would have the script hidden, and none of the students (besides me, and i know the password) would have any knowledge of looking at the script. it would be hidden anyway.

edit- i reread your post and saw it can be taken two ways, if the top isnt true , just ignore it .

'bless' would get the job done in a shell script embedded in an Applescript, but each script might need to be machine-specific depending how the volumes are named, unless it's to be a fairly complex script.

I was assuming that each machine had an OS 9 volume, correct?

Try a little script like this to see what happens:

do shell script "sudo bless (whatever the parameters are)"
ignoring application responses
tell app "System Events" to restart
end ignoring

I don't know how to use the bless command - we shall have to ask JJ. Another question I had was how to do a sudo programatically - it's going to ask for the password unless you use "passwd" to tell it to get passwords from a file, which you can make secure.

Also, we can make the AppleScript a run-only, which means it forever can't be opened in the Script Editor (which really just decompiles the bytecode). But the students could try using a text editor to find the password in the AS file. You said it would be hidden - you can make it execute-only and not readable or writable?

The syntax for 'bless' would look like this:

sudo bless -folder9 <path to OS9 folder goes here> -setOF

How does he get past the password that sudo is going to ask for?

said by File Quit:k, and johnny, how can i make this into a unix script to make it restart after. i now understand the bless command fully, thanks JJ!

Just use the Applescript I showed above. It first tells AppleScript to run JJ's unix script to do the blessing; then it tells the app "System Events" to restart the machine, ignoring all "close file" and so forth messages. If you want those messages to appear, take out the "ignoring and end ignoring" statements. Of course, if after the restart command is given by the script, then if the restart is interrupted by a dialog box, can the students choose "restart" manually?

I guess we'll leave out the 'sudo' part of the commmand and use the 'setuid' trick to get the script to run as root. Naughty but effective.

Create the script, e.g.

#!/bin/sh
bless -folder9 <path to OS9 folder goes here> -setOF
(note there's <b>no</b> 'sudo')

then download X-Ray and use it to: make the script executable by owner, group, and world; set the owner to root (use 'wheel' for the group); and set the 'setuid' bit. What you will have is a script that can be executed by anyone (including the Applescript) and does not require a password.
