Hey guys
Just need some help with crontab.Iam looking for a script that will alert particular user about its change through sendmail.We are using bash here.

I'm sure there are many ways to do it. One would be to watch the MD5 of the file, and send a mail when it changes.

ORIGMD5=`crontab -l | md5sum`

while ( true )
do
   NEWMD5=`crontab -l | md5sum`
   if [[ "$ORIGMD5" != "$NEWMD5" ]]
   then
      echo "crontab changed" | mail you@example.com
      ORIGMD5=$NEWMD5
   fi
   sleep 60
done

Thank You PXT.
