FTP on cron: how to be silent except errorsHelpful Member!

I made a cron script to do some backups and FTP them offsite.  Everything is running fine, but I still get an email with "Interactive mode off."  Here is the relevent part of my script:

CODE

ftp -n $REMOTESERVER <<INPUT_END
quote user $LOGIN
quote pass $PASSWORD
prompt off
put myfile1.tar.gz
put myfile1.tar.gz
exit
INPUT_END
I don't want to send the whole output to /dev/null or something, because I want to be notified if there are errors.  But I also don't want this useless email every night.  I tried just doing "prompt off > /dev/null", but it didn't shut it up.  Suggestions?

you could try just rerouteing stdout

ftp -n $REMOTESERVER 1>/dev/nul <<INPUT_END

if it is stderr you need to reroute then use 2> instead.

Thanks!  I was forgetting that STDOUT and STDERR are separate, and I didn't realize that I needed to do the redirect for the whole ftp command, not the commands inside that (which are not commands to the shell but to ftp).

Aside: For the sake of future readers, the spelling seems to be null, not nul, and the 1 is technically optional (STDOUT is the default).
