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)
