inc Command

Purpose

Files new mail in a folder.

Syntax

inc [ + Folder ] [ -noaudit | -audit File ] [ -changecur | -nochangecur ] [ -form FormFile | -format String ] [ -help] [ -file File ] [ -truncate | -notruncate ] [ -nosilent | -silent ] [ -width Number ]

Description

The inc command files incoming mail in a specified folder and outputs a list of the messages filed. A folder is a system directory. By default, the inc command removes the new messages from your mail drop and places them in the specified folder. To file new mail without deleting the mail drop, use the -notruncate flag.

If the specified folder does not exist, the inc command prompts you for permission to create it. The system creates the folder as a subdirectory of the user's Message Handler (MH) directory. The default folder is inbox.

Note: If you do not have a Path: entry specified in your .mh_profile file, the inc command creates the folder as a subdirectory of the current directory.

Filed messages are assigned consecutive message numbers starting with the next highest number in the folder. Each new message receives the protection code specified in the Msg-Protect: entry in your .mh_profile file. If the Msg-Protect: entry does not exist, a protection code of 644 is assigned. If the Unseen-Sequence: entry exists, new messages are added to each sequence specified by the entry.
