Yes, that is action script. If you’re not already familiar with it, then Distribution might be best.
@JasonWalker’s advice in this other thread might be instructive.
I suggest starting with a simple shell script that sends output to a file, so that you can see what’s going on when Distribution executes a shell script.
- Start with a script that only touches a file; does that work?
- Have the script print its working directory to an output file. That tells you the file path where Distribution executes from.
- Have the script print the location of the script itself. (You can do this with bash variables.)
- etc.
Having built the familiarity about Distribution’s shell environment, an adept shell scripter should be able to make the installer do what it needs.
(Unfortunately, I think you’ve discovered that using shell scripts with Distribution isn’t a common usecase on the forum.)
