actually here is the latest script:
#!/bin/bsh
#################################
for file in `cat iplist.txt`
do
ping -c 1 -A $file | grep errors | wc -l
read tom
echo $tom
if [ "$tom" != 0 ]
then
mail -s"Test" exx@xx.com
else
mail -s"Worked" exx@xx.com
fi
done
For starters, make sure that iplist.txt is in the correct directory. I assume it will always be in the same directory as the script? If not, add a path to the file name. Second, for the mail portion, try using sendmail as this is commonly installed on RedHat. To check the status of the ping command, use a variable to capture the status. Not sure what the return value is of that ping command, adjust the IF statement to match.

for file in `cat iplist.txt`
do
PING_TEST=0
PING_TEST=`ping -c 1 -A $file | grep errors | wc -l`
#read tom
#echo $tom
if [ $PING_TEST -ne 0 ]
#Use -ne (not equal) for integer comparison
then
sendmail -s"Test" exx@xx.com
else
sendmail -s"Worked" exx@xx.com
fi
done

NAME

       script-email - Amanda script to send email notifications

DESCRIPTION

       script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the
       addresses specified in the MAILTO property.

PROPERTIES

       This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       MAILTO

	   List of email addresses that will receive an email on command execution. It is a multi-valued property:
	     property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com"

EXAMPLE

       In this example, script-email is scheduled to be run before the DLE, on the server.  The unqualified email address amanda will be passed to
       the email system unchanged.  The script is then attached to a dumptype, which can then be specified for any DLEs which require
       notification.
	define script-tool pre-email {
	  comment "email me before this DLE is backed up"
	  plugin  "script-email"
	  execute-on pre-dle-backup
	  execute-where server
	  property "mailto" "amanda"
	}

	define dumptype user-tar-email {
	  user-tar
	  script "pre-email"
	}
