-Devaraj Takhellambam
thanks for your response..Actually i am new to shell scripting
Code:
FILE="/opt/server.conf"
NEW_FILE="/opt/new_server.conf"
        
 IFS=""
        for line in `cat ${FILE}`; do
        #echo ${line}
        if [ -n "`echo ${line} | grep 'Server=127.0.0.1'`" ]  #grep command searches for right string
        then
                 echo ${line} | sed 's|Server=127.0.0.1|Server=0.0.0.0|g' >>$NEW_FILE
        elif [ -n "`echo ${line} | grep 'ServerPort=0'`" ]
        then
                echo ${line} | sed 's|ServerPort=0|ServerPort=1|g' >>$NEW_FILE
        elif [ -n "`echo ${line} | grep 'Enable Server=1'`" ]
        then
                echo ${line} | sed 's|Enable Server=1|Enable Server=0|g' >>$NEW_FILE
        else
                echo ${line} >>$NEW_FILE
        fi

net::server::proto::unix

Net::Server::Proto::UNIX(3)				User Contributed Perl Documentation			       Net::Server::Proto::UNIX(3)

NAME

       Net::Server::Proto::UNIX - Net::Server UNIX protocol.

SYNOPSIS

       See Net::Server::Proto.

DESCRIPTION

       Protocol module for Net::Server.  This module implements the UNIX SOCK_STREAM socket type.  See Net::Server::Proto.

       Any sockets created during startup will be chown'ed to the user and group specified in the starup arguments.

PARAMETERS

       The following paramaters may be specified in addition to normal command line parameters for a Net::Server.  See Net::Server for more
       information on reading arguments.

       unix_type
	   Can be either SOCK_STREAM or SOCK_DGRAM (default is SOCK_STREAM).  This can also be passed on the port line (see Net::Server::Proto).

	   However, this method is deprecated.	If you want SOCK_STREAM - just use proto UNIX without any other arguments.  If you'd like
	   SOCK_DGRAM, use the new proto UNIXDGRAM.

METHODS

       NS_unix_path/NS_unix_type
	   In addition to the standard NS_ methods of Net::Server::Proto classes, the UNIX types also have legacy calls to NS_unix_path and
	   NS_unix_type.

	   Since version 2.000, NS_unix_path is simply an alias to NS_port.  NS_unix_type is now redundant with NS_proto.

	   These methods were missing between version 2.000 and 2.003 but have been returned as legacy bridges.

QUICK PARAMETER LIST

	 Key		   Value		    Default

	 # deprecated UNIX socket parameters
	 unix_type	   (SOCK_STREAM|SOCK_DGRAM) SOCK_STREAM
	 port		   "filename"		    undef

	 # more recent usage
	 port		   "filename / UNIX"
	 port		   "filename / UNIXDGRAM"
