NEXT(1)                                                              [nmh-1.5]                                                             NEXT(1)

NAME

       next - show the next message

SYNOPSIS

       next [+folder] [-showproc program] [-showmimeproc program] [-header | -noheader] [-checkmime | -nocheckmime] [switches for showproc or
            showmimeproc] [-version] [-help]

DESCRIPTION

       Next performs a show on the next message in the specified (or current) folder.  Like show, it passes any switches on to the  program  show-
       proc  or  showmimeproc, which is called to list the message.  This command is almost exactly equivalent to "show next".  Consult the manual
       entry for show(1) for all the details.

FILES

       $HOME/.mh_profile          The user profile

PROFILE COMPONENTS

       Path:                To determine the user's nmh directory
       Current-Folder:      To find the default current folder
       showproc:            Program to show non-MIME messages
       showmimeproc:        Program to show MIME messages

SEE ALSO

       show(1), prev(1)

DEFAULTS

       `+folder' defaults to the current folder
       `-checkmime'
       `-header'

CONTEXT

       If a folder is specified, it will become the current folder.  The message that is shown (i.e., the next message in  sequence)  will  become
       the current message.

BUGS

       next  is  really  a link to the show program.  As a result, if you make a link to next and that link is not called next, your link will act
       like show instead.  To circumvent this, add a profile-entry for the link to your nmh profile and add the argument next to the entry.

MH.6.8                                                             11 June 2012                                                            NEXT(1)
