I'm calling a bash shell script (which I wrote) with "do shell script"
within a try block. If the shell script does an "exit" with a non-zero
value then I enter the "on error" portion of the try block. The error
number returned to AppleScript is the number I exited with and the
error message text is something like "An error of type <my exit number>
has occurred."
Is there a way to set the error message _text_ within the shell script
(prior to my "exit" statement) such that the message that gets returned
to AppleScript is more meaningful?
I tried redirecting an echo statement to stderr but that didn't seem to
work. It seems like I figured out how to do this at some point in the
past, but I couldn't locate that old code. Is there possibly a shell
variable that contains error message text that I can set?
