Create custom shutdown message?

Thanks so much for the links. I searched but could not find anything like this. However, I'm still thinking this could not help my problem. I'm a bit of a noob in scripting/terminal use, so I'm not sure but what I think I need is to actually change/alter the shutdown message to tell the user a list of actions that should be done (not even related to the computer necessarily but to the shutdown sequence of the recording studio overall). The more I dig into this the more this seems unreasonable and impossible. Please correct me if I'm wrong. Thanks for the help,

Greg

Thanks BDAqua, so me being a big noob at this, I would create a file with this?:



#!/bin/sh

. /etc/rc.common

StartService ()
{
# what to do on boot (can be empty)
}

StopService ()
{
# Please power down master fader on mixing console.
}

RunService "$1"



I just add what I want the user to do there?

In the thread he says "place a file of the same name as the directory...". I am unsure of how to do this or exactly what this means. I create a folder with a name, then create a file with the same name as the folder, and the file must be an executable file? I don't know how to create an executable. :/

Then I create a text file called "StartupParameters.plist" with the following script:

{
Description = "Name of your service goes here";
Provides = ("Whatever your service provides goes here");
Uses = ("Disks");
}


The "Description" and "Provides" scripts, are these arbitrary? Just descriptions or do I need to give some kind of script direction here.

Again, you can see my noob-ness, but thanks for helping!
