Without a better explanation of what you're trying to do, it is hard to give a good answer.

If you want to delete all but the last 3 words on every line, or delete the first 2 words on every line, we can make suggestions that will help. If you want to delete everything but a few recognized words (and can't or won't tell us which words are "recognized"), it becomes much harder for us to make any useful suggestions.

If you can show us a representative sample input file and explain how you want to modify that text and show us the output you hope to produce, we can do a much better job of making useful suggestions.

prompter(1mh)															     prompter(1mh)

Name
       prompter - prompting editor front-end

Syntax
       prompter [ options ] file

Description
       The editor is a rudimentary editor provided by and It is automatically called by the above commands; you do not need to specify it.

       The editor allows rapid composition of messages.  It is particularly useful to network and low-speed (less than 2400 baud) users of MH.

       The editor is an MH program.  Although is not invoked directly, it can have its own profile entry with options; see The and commands invoke
       in one of three ways: when invoked with the -editor prompter option; by an entry in the file; or by a command at the What now? prompt.	If
       you do not specify an editor in any of these ways, MH provides as the default editor for all of these commands.

       For information on how to use a different editor with MH commands, see the reference pages for the appropriate commands, and also

   Composing a Message with prompter
       When  you  create  a message with an MH command, the mail system provides a message template for you to fill in.  This template consists of
       two parts: the message header, comprising a number of header fields; and the body of the message, which is the area where you type the text
       of your message.

       The  editor  displays  each header field, one at a time, for you to fill in.  Fill in the component by typing the text that you want.  Type
       <RETURN> to move onto the next component.  Once you have moved on from a header field, you cannot edit what you have entered.

       If you want to leave a header field empty, simply type <RETURN>.  You can continue a header field over one line by typing a back-slash  ()
       before the <RETURN>.  Continuation lines must start with a blank (a space or a tab).

       The  start  of  the message body is indicated by a blank line or a line of dashes.  If you are creating a new message, the cursor is placed
       beneath this line to allow you to enter text.  If there is already some body text in the message (for example, if you are using an existing
       draft, or if you are forwarding a message), you will receive a prompt:
	   --------Enter additional text
       or:
	   --------Enter initial text
       The cursor is placed under the prompt to allow you to enter text.

       To finish the message, type <CTRL/D>.  You will then receive a prompt asking What now?.	See for more details of responses.

       An  interrupt,  usually	<CTRL/C>, during component typing will abort and the MH command that invoked it.  An interrupt during message-body
       typing is equivalent to <CTRL/D>, for historical reasons.

Options
       -prepend
       -noprepend
		 Adds text to the beginning of the message body, so that the rest of the body follows.	This is useful for the command.   You  can
		 suppress this behavior by using the -noprepend option.

       -rapid
       -norapid  Causes  the text not to be displayed on your terminal if the draft already contains text in the message-body.	This is useful for
		 low-speed terminals.  You can suppress this behavior by using the -norapid option.

       -erase char
		 Specifies the line-editing characters, where char may be a character or 
nn, where nnn is the octal value for the character.

       -kill char
		 Specifies the line-editing characters, where char may be a character or 
nn, where nnn is the octal value for the character.

       The first argument to which is not an option is taken as the name of the draft file, and subsequent non-flag arguments are ignored.

       The default settings for are:

	      -prepend
	      -norapid

Restrictions
       The editor uses therefore do not edit files with nulls in them.

Profile Components
       prompter-next:	To name the editor to be used on exit from prompter
       Msg-Protect:	To set protections when creating a new draft

Files
       The user profile.

       Temporary copy of message.
