What search string did you use to find that? That may be more interesting than
my original question.
Reading that page, I found the explanation that an exit through a trap might
give a different exit status with a simple
exit 1
because the exit status will be that of a command run in the trap and the more
complex
{ (exit 1); exit 1; }
preserves the intended exit status. But I don't understand that. It seems to
me that if that unintended exit status obtains with the simple command, it will
with the more complex command too. Evidently either I misunderstood the Web
page or I'm missing something.
