It sounds as though you're saying you want "the normal
script output" when run under some circumstances, rather
than the output you observe when running as cron. While
there are a number of ways to approach this, I'd invest-
igate how to make cron processes behave as "normal" ones.
It's likely you just need to set the TERM environment
variable or some other one-liner.
Expect FAQs frequently involve cron.
