NAME

     readmsg - extract messages from a mail folder



SYNOPSIS
     readmsg [-anhp] [-f folder] [-w weedlist] [selection ...]



DESCRIPTION
     Readmsg extracts selected mail messages from a mail  folder.
     One  helpful  use of the program is when you are composing a
     response to a mail message in an external editor.   In  this
     case,  you  can  run  readmsg to pull a copy of the original
     message into the editing buffer.

     When you run readmsg from within elm (e.g. from  a  subshell
     escape  or  in  an  external  editor  while composing a mail
     reply) it behaves a bit differently from  when  you  run  it
     directly  (e.g.  from  a shell command line).  We will first
     describe its normal behavior, and then describe  how  it  is
     different when you run it under elm.

     You tell readmsg which messages to extract with  the  selec-
     tion  argument.   There  are  a couple of possible different
     ways to specify the selection.

     1.   A lone ``*'' means select all messages in the mailbox.

     2.   A list of message numbers may be specified.  Values  of
          ``0''  and ``$'' in the list both mean the last message
          in the mailbox.  For example:

               readmsg 1 3 0

          extracts three messages from the  folder:   the  first,
          the third, and the last.

     3.   Finally, the selection may be some text to match.  This
          will  select  a  mail message which exactly matches the
          specified text.  For example,

               readmsg staff meeting

          extracts the message which contains the  words  ``staff
          meeting.''   Note that it will not match a message con-
          taining ``Staff Meeting''  the matching is case  sensi-
          tive.   Normally  only  the first message which matches
          the pattern will be printed.  The -a  option  discussed
          in a moment changes this.

     The -f flag indicates  that  you'd  rather  use  the  folder
     specified  rather  than  the  default incoming mailbox.  The
     specified folder can be a filename or a  specification  such
     as ``=sentmail''.
     The -w flag tailors the list of mail headers that are weeded
     and displayed.  Header weeding is discussed below.

     The -h flag instructs the program to ignore the header weed-
     ing  list, and include the entire header of the matched mes-
     sage or messages when displaying their text.

     The -n flag instructs the program to ignore the header weed-
     ing  list, and exclude all headers.  This is used mostly for
     extracting files mailed and such.

     The -p flag indicates that the program should put form-feeds
     (control-L) between message headers.

     The -a flag indicates that all messages which match the pat-
     tern  specified  on  the command line should be printed, not
     just the first.  If a pattern was not specified on the  com-
     mand line then this flag has no effect.

     When you run readmsg under elm (say in  the  context  of  an
     external  editor)  the  behavior will be different from that
     described above as follows.

     1.   The default mail folder will  be  the  folder  you  are
          currently  examining  in  elm  and not necessarily your
          incoming mail folder.

     2.   You do not need to specify a selection on  the  command
          line.   If  you  omit  the  selection then readmsg will
          extract the message(s) you have selected  in  Elm.   If
          you  have tagged any messages then this would be all of
          the tagged messages, otherwise it would be the  message
          you are currently examining.

     3.   Normally the message numbers readmsg uses are in  mail-
          box  order.  When you call readmsg under elm and do not
          override the folder selection with the -f option,  then
          message numbers will be sorted as they are displayed on
          the elm message index screen.

     Normally, readmsg selects and displays certain headers  from
     the  message.   By  default,  the  list  of selected headers
     includes:

          o The ``Subject:'' header.
          o The ``From:'' header.
          o The ``To:'' header.
          o The ``Cc:'' header.
          o The ``Date:'' header.
          o Any header starting with ``Apparently-''.


     The header weeding may be changed with the -w  option.   The
     argument to this option is a list of header names, separated
     by whitespace or commas.  readmsg compares  each  header  to
     the ones in this list, and if a match is found the header is
     displayed.  The list  entries  can  contain  partial  header
     names.   For instance, an entry of ``From'' would match both
     the ``From<SPACE>'' line at the top of the message, as  well
     as  any ``From:'' header.  Matching is case insensitive.  An
     underscore (``_'') may be used  to  represent  a  space,  so
     specifying  ``From_''  will  select the ``From<SPACE>'' line
     but not the ``From:'' header.  A list entry may be  preceded
     by  an  exclamation  point  to suppress the header.  Thus, a
     specification of ``!From_ From'' means about the same  thing
     as ``From:''.  When no header weeding options are specified,
     the default action corresponds to:

          readmsg -w "Subject: From: To: Cc: Apparently- Date:"



EXAMPLES
     First off, to use this from within vi to include the text of
     the current message, you could use the command:

          :r !readmsg

     (as you hit the ':' the editor will put you at the bottom of
     the  screen  with the ':' prompt).  The space following ':r'
     is required.


     Let's look at something more interesting, however;

     Suppose you have the mail file;

        From joe Jun 3 1986 4:45:30 MST
        Subject: hello

        Hey Guy!  Wanta go out and have a milk this evening?

        Joe

        From john Jun 3 1986 4:48:20 MST
        Subject: Dinner at Eight
        From: John Dinley <xyz!john>

        Remember you should show up about eight, okay?

                  - John D -

        From xxzyz!cron Jun 3 1986 5:02:43 MST

        Cannot connect to server: blob
        Job 43243 deleted from queue.

     The following commands will result in;

       $ readmsg 2
       [ display the second message, from John ]

       $ readmsg
       [ an error, unless we're calling from elm ]

       $ readmsg BLOB
       [ no match - case sensitive! ]

       $ readmsg -h connect to server
       [ displays third message, including headers ]




FILES
     /usr/mail/<username>          The incoming mail
     $ELMSTATE           Status information from elm

BUGS
     The '*' metacharacter doesn't always work as expected!
     Perhaps the pattern matching should be case insensitive?
     It might be confusing that messages are sorted when  running
     under  elm with the current folder, and in mailbox order for
     all other cases.  When readmsg is run  standalone,  messages
     may  be  truncated  at lines beginning with "From".  This is
     not a problem when readmsg is spawned under elm because  the
     status information file created by elm says exactly how long
     each message is.
