If I have errors I send it to a file. Looking at the email I get from this particular job I don't see any reason to log it. 00,15,30,45 * * * * /home/marpace/bin/scanftp.rxx 2> /home/marpace/scanftp.err
So sending the output to null would be 00,15,30,45 * * * * /home/marpace/bin/scanftp.rxx > /dev/null 2> /home/marpace/scanftp.err That look correct? On Thu, Aug 5, 2010 at 12:51 PM, Edmund R.
