Hi Akshay and wisecracker:
I modified the CODE tags in the 1st message in this thread to make the input and output differences easier to see, but even with that fix, it seems that none of you noticed that four fields changed.

With four unrelated changes and no description of how the desired output could be derived from the input, it seems to me that the easiest thing for learnbash to do is to manually edit the input file. In case you didn't notice, the requested output (with the differences marked in red) are:
Code:
18011325      ; serial number YYMMDDNN

m.abcd.com.             600     IN      A       10.20.124.100

Why write a script to make four unrelated changes once?

syslog_evm.conf

syslog_evm.conf(4)					     Kernel Interfaces Manual						syslog_evm.conf(4)

NAME

       syslog_evm.conf - EVM syslog subscription configuration file

SYNOPSIS

       facility.priority

DESCRIPTION

       The  syslog_evm.conf file is a text file that specifies what syslog messages will be forwarded from the syslog daemon to the Event Manager,
       EVM,in the form of EVM events.  Those syslog messages are posted to the EVM daemon evmd by syslogd if the syslogd  forwarding  function	is
       turned on with the -e flag.  Events are posted with the EVM name of sys.unix.syslog.facility-name.

       This configuration file is read every time syslogd starts, or is restarted by a SIGHUP signal.  If the file does not exist, or if it exists
       but contains no subscription lines, no syslog messages will be posted to EVM.

       Each line in the file controls the forwarding of one syslog event.  Lines beginning with the # character are considered	comments  and  are
       ignored.  Only one subscription per line is permitted.  Mixing a subscription and a comment on the same line is not allowed.

       Each  line has the format facility.priority[+].	Specifies the part of the system that generated the message.  Legal values are the follow-
       ing: All messages.  Messages generated by the kernel.  Messages generated by user processes.  Messages generated by the mail system.   Mes-
       sages  generated  by  system  daemons.	Messages generated by the authorization system.  Messages generated internal to the syslog system.
       Messages generated by the line printer spooling system.	Messages generated by the system news command.	Messages generated by the UNIX	to
       UNIX  copy  system.   Messages  generated by the system clock daemon.  Messages generated by remote file systems.  Available for local use.
       Indicates the priority of the message.  If the priority is followed by a + character, events which are of the specified priority or  higher
       are forwarded; otherwise only events which exactly match the priority are forwarded.

	      The priority level must be one of the following: Forward messages of any priority.  Forward messages of emergency priority.  Forward
	      messages of alert priority.  Forward messages of critical priority.  Forward messages of error priority.	Forward messages of  warn-
	      ing priority.  Forward messages of notice priority.  Forward messages of information priority.  Forward messages of debug priority.

EXAMPLES

       This  example causes syslogd to forward events to EVM as follows: All messages of emergency priority are forwarded.  All messages generated
       in the kernel which have a priority of info or greater are forwarded.  All messages generated by users, by the mail  subsystem  or  by  the
       system daemons which have a priority of info or greater are forwarded.

       *.emerg kern.info+ user.notice+ mail.notice+ daemon.notice+

FILES

       Location  of the system logger configuration file.  Location of the EVM syslog subscription configuration file.	Location of the EVM logger
       configuration file.
