replacing strings with newlines : sed
Hi everyone,

Since the previous time I received help from unix.com I have been encouraged to learn more.

going through 1 of the articles(View Article) on sed I found, it pointed an interesting situation.
Suppose the text is :

Romeo and Ethel the Dancer Moves Audience to Tears.
I was treated to the off Broadway opening of Romeo and Ethel the
Dancer. This moving story of star-crossed lovers had the
audience in tears half way through the third act.
Do not go to see this play without a hanky, but even the weeping
from the back row could not diminish the brilliance of Romeo and
Ethel the Dancer by William Shakespeare.

Now I want to replace "Romeo and Ethel the Dancer" by "Romeo and Juliet".
The lines are separated by newlines.

The article demontrates doing this by using addresses. I was trying to think of another way round by building a reg-ex and use simple sed.
I believe I need a way to represent a newline in the sed search expression.

Please help by hinting towards the solution and not directly.

Thank You.

Regards

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user  object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to  the  server,  nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
