Text from script..

Answer 1

Redirect the output to dev null as part of the command
So the cron command you'd run would be blah > /dev/null
To filter for some, you can use the pipe "blah | either awk or grep"

Answer 2

Here is a bash script...
#!/bin/bash
awk ' BEGIN {flag=1}
{
if ($0 ~ /Date:/) { flag=0;
}
if ($0 ~ /From/) { flag=1;
}
if (flag==0) {print}
}
'
