Hi Ed,
A few quick pointers should get you going in the right direction.

First, your cron job will run at 20 after the hour and only once per hour. If you want to run it every 20 minutes you should have a cron entry like this:

0,20,40 * * * * perl blah blah blah

This will run at the top of the hour, 20 after, and 40 after.

Second, your script is running but is directing the output of cat to a file called 'mail'. Try running 'perl /var/dir/script.pl | cat update.email >> mail ed@ed.com' from command line. I don't think you will get the results you want.

I think a better approach would be to put the 'cat' and 'mail' commands in your perl script or write a ksh/csh/sh/bash/etc wrapper script that first runs the script.pl and then 'mail ed@ed.com<<update.email'. Notice the mail syntax change. This will e-mail you the file where your previous command was basically creating a copy of upate.email called mail.

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"
	}
