It sure does. Great input, thanks much. Apologies for not having checked the tech note.

Since top is normally interactive and you don't need that I'd use the -l flag to run it only once. The tech note for do shell script even cites this interactive shell app as an example of problems and limits of these apps.
And I get the same result from...


do shell script "top -tl 2 -o cpu -p '$aaaaaa $cccc ^bbbbbbbbbbbbbbbb'"

	as I do from...

do shell script "top -l1 -tl 2 -o cpu -p '$aaaaaa $cccc ^bbbbbbbbbbbbbbbb'"

	Does that help the issue?

Sincerely, I think that programming "do shell script" was a tricky business and using it with "top" unveals some kind of a limit.

Not so sure. If I run do shell script "mkdir foo/bar" (no -p) the error says
"no such file or directory" - it's an error from the command - not "The
command exited with a non-zero status".

Ah, I see. So it's exiting with a nonzero status without sending an
error message to stderr. In that case, without redirecting stderr to
dev null, I can't think of any way to reproduce that. It could occur
if something terminated mkdir before it completed, perhaps, but most
error conditions would yield an error message either from mkdir or
from bash.
