I have searched the forum and seems like I
just don't quite find my question.
I have a script that runs out of cron and I
am trying to send normal successful stdout
to /dev/null, but if there is an error, I
want both stdout/stderr to go to mail.
In other words, I only want to know about
it if there is a problem (error), then I want
to see both stdout/stderr.
If I understand correctly, the following sends both
stdout and stderr to /dev/null:
>/dev/null 2>&1
The following sends stdout and stderr to the same place,
mail in my case.
2>&1
I guess I don't understand enough to make this happen
or even if it's possible.
Any advice is appreciated.
Thanks.
