prev - show the previous message (only available within
the message handling system, mh)
prev [+folder] [-[no]header] [-help] [-showproc program]
[-noshowproc] [options to showproc]
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. Prints a list of the valid options
to this command. Specifies an alternative program to list
messages. The default is to use the program defined by the
showproc: entry in the 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
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.
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.
