In Apple's TN2065 [1], regarding 'do shell script', I read:
"If the script printed something to the standard error stream, that

becomes the error message in AppleScript."
What is the "error message" in AppleScript? How can I set a
variable to it?
The error message shows up as a thrown exception, but only if the
shell command indicated an error via nonzero exit code. You can force
that by sticking an exit command at the end of the pipeline. Ex:
try
do shell script "echo >&2 boo; exit 0"
on error e
set theMessage to e
end try
theMessage -- "boo"
...except that, as Mark implies, the number after the "exit" has to be
something other than 0. On the other hand, using "exit 0" can be
handy for suppressing shell script errors.
