The word “Script” was a title reference, not a command!
Not using sudo or root, but your basic user ID, in a terminal, you need to enter the command:
Appl__Command__PathAndPrecedence.sh firefox
Also, you should already know this, but you should NEVER run a script without first going thru the logic to confirm for yourself that there a no “mischievious” intents.
IMPORTANT:
Please note that if you are not familiar with basic UNIX/Linux Shell programming, you need to read up a bit on that VERY urgently before you accidentally enter a command that will have irrevocable consequences!
OK, I will look into shell programming before taking this any further. Its probably best if I close this topic for the time being, I’ve got other things to do!
