I have 100 scripts under a specific user id(dgircc) in cron .SO inrder to check the whether the script has sucessfully run or not and if not to generate an email
if i mention the code like

Code:

#!/bin/ksh -p
     2  fsize=`ls -lrt /var/mail/dgircc |awk '{print $5}'`
     3  if [ $fsize -gt 0 ] ;then
     4  more /var/mail/dgircc >> /var/mail/dgircc.old
     5  uuencode /var/mail/dgircc /var/mail/dgircc | mailx -s "dgircc report "  mailid 
     6  cp /dev/null /var/mail/dgircc
     7  fi

will this solve my requirement
Please let me know if there are any good ideas to monitor all the scripts under cron which has failed and to generate a consolidated report of those(which are failed) .
