Hi All,

Thanks for ur suggestions.Sorry for late reply
I followed otheus suggestion and put the code, but it going to infinite loop and not getting any output. I am new to UNIX, so i may be wrong in some pattern.
Code i am using

#!/bin/sh
tail -f EssbaseLog.txt | awk '
BEGIN { email_cmd = "mail -s failure xxxxx@yyy.com" }
BEGIN { last_found = "NOT AVAILABLE"; last_lineno = 0; }
/[hyperion]/ { last_found = $0; last_lineno = FNR; }
/Error -- not connected/ { print "Found " (FNR-last_lineno) " lines ago:" last_found }'


I have questions on this, as i mentioned if i get error at 2:30 PM, my script will execute and send a report to users.It should also save a text file with that 50 lines for reference.

Then if it runs again on 2:45 it will again send the same error message and it will continue to send the error until log was corrected.

Is there any way we can send only updated errors?

Sorry for amny questions

Any suggestions will be appreciated

Thanks

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" } SEE ALSO
