Does that code start splitting from 480th position i.e. 6th record and work backwards? Apologies for the stupid question but where is it matching the delimiter?

The file can be of any length, ie have any number of records. The records in the file are also of variable length so the only way to identify the end of a record is that it is after each 81st occurrence of the "^@" delimiter.

Ie from the start of the file till 81st delimiter is one record, 82nd till 163rd is the second record, and so on.

The records are currently all in one line and they need to be in multiple lines ie separated by \n

Is there a way to do the 81st delimiter check till end of file

praudit

praudit(1M)						  System Administration Commands					       praudit(1M)

NAME

       praudit - print contents of an audit trail file

SYNOPSIS

       praudit [-lrsx] [-ddel] [filename...]

DESCRIPTION

       praudit	reads  the  listed  filenames  (or  standard input, if no filename is specified) and interprets the data as audit trail records as
       defined in audit.log(4). By default, times, user and group IDs (UIDs and GIDs, respectively) are converted to their  ASCII  representation.
       Record  type  and  event  fields  are converted to their ASCII representation. A maximum of 100 audit files can be specified on the command
       line.

OPTIONS

       The following options are supported:

       -ddel	Use del as the field delimiter instead of the default delimiter, which is the comma. If del has special meaning for the shell,	it
		must  be  quoted. The maximum size of a delimiter is three characters. The delimiter is not meaningful and is not used when the -x
		option is specified.

       -l	Print one line per record.

       -r	Print records in their raw form. Times, UIDs, GIDs, record types, and events are displayed as integers. This  option  and  the	-s
		option are exclusive. If both are used, a format usage error message is output.

       -s	Print  records	in  their short form. All numeric fields are converted to ASCII and displayed. The short ASCII representations for
		the record type and event fields are used. This option and the -r option are exclusive. If both are used,  a  format  usage  error
		message is output.

       -x	Print records in XML form. Tags are included in the output to identify tokens and fields within tokens. Output begins with a valid
		XML prolog, which includes identification of the DTD which can be used to parse the XML.

FILES

       /etc/security/audit_event       Audit event definition and class mappings.

       /etc/security/audit_class       Audit class definitions.

       /usr/share/lib/xml/dtd	       Directory containing the verisioned DTD file referenced in XML output, for example, adt_record.dtd.1.

       /usr/share/lib/xml/style        Directory containing the versioned XSL file referenced in XML output, for example, adt_record.xsl.1.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
