I am sorry for not stating my requirement properly , We are trying to accomplish incremental load of data by comparing two files

File 1
Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 14 | abc@sample.txt
657342|this is line 3 | def@sample.txt

File 2

Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 2 | abc@sample.txt


I would like output by comparing above two files which should display below results
Desired Output:
-------------------
Code:
 id   | text       | email id 
---------------------------------
89564|this is line 1 | xyz@sample.txt
985384|this is line 2 | abc@sample.txt | modified (Note :  second column got modified ) 
657342|this is line 3 | def@sample.txt | deleted

Here we are trying to compare two files and if we don't find a record in file 2 based on column 1 ( primary key ) we treat that entry as deleted and we generate a new file with its operational code(in this case deleted). Similarly we if we find record in both the files ( file 1 and file2) we would still have that record in file 3 ,and for modified if we see any column modifies in file 2 we add the entry as modified .

SCRIPT-EMAIL(8) 					  System Administration Commands					   SCRIPT-EMAIL(8)

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"
	}
