Hi,
I'm trying to call execresult with a command which can produce slightly
different output each time. In the process I realized that it seems to
be called multiple times. Is this behavior by design?
Is there some way I can evaluate a command -once- and retain the output
in a variable?
(see below for a simple promises.cf, with sample output).
Thanks,
Ian
