prev(1)
NAME
  prev - show the previous message (only available within the message
  handling system, mh)

SYNOPSIS
  prev [ +folder ] [ -[no]header ] [ -help ] [ -showproc program ] [
  -noshowproc ] [ options to showproc ]

DESCRIPTION
  The prev command displays the previous message in the current folder.	 The
  previous message is the one before the current message in the folder.	 The
  message that is shown becomes the current message.

  You can specify a folder other than the current folder by using the +folder
  argument.  If you specify a folder, that becomes the current folder.

FLAGS
  -header
  -noheader Displays a one-line header before the message.  The header
	    consists of the name of the folder and the message number.	This
	    is the default behavior.  It can be suppressed with the -noheader
	    option.

  -help	    Prints a list of the valid options to this command.

  -showproc program [ options ]
  -noshowproc
	    Specifies an alternative program to list messages.	The default
	    is to use the program defined by the showproc: entry in the
	    .mh_profile file.  As with show, you can give options to the
	    showproc program at the command line. These are passed directly
	    to showproc by prev.

  The defaults for this command are:

       +folder defaults to the current folder
       -header

RESTRICTIONS
  The prev command is really a link to the show program.  As a result, if you
  make a link to prev and that link is not called prev, your link will act
  like show instead.  To avoid this, add a profile-entry for the link to your
  MH profile and add the argument prev to the entry.

EXAMPLES
  The command in the following example displays the previous message in the
  folder +copylog:

       $ prev +copylog

PROFILE COMPONENTS
  Path:	      To determine your Mail directory
  showproc:   Program to show the message

FILES
  $HOME/.mh_profile
	    The user profile.
