NAME
prev - show the previous message SYNOPSIS
prev [+folder] [-showproc program] [-showmimeproc program] [-header | -noheader] [-checkmime | -nocheckmime] [switches for showproc or showmimeproc] [-version] [-help] DESCRIPTION
Prev performs a show on the previous message in the specified (or current) folder. Like show, it passes any switches on to the program named by showproc or showmimeproc, which is called to list the message. This command is almost exactly equivalent to "show prev". 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), next(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 previous message in sequence) will become the current message. BUGS
prev 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 circumvent this, add a profile-entry for the link to your nmh profile and add the argument prev to the entry. MH.6.8 11 June 2012 PREV(1)
