packf Command

Purpose

Compresses the contents of a folder into a file.

Syntax

packf [ +Folder ] [ Messages ] [ -file File ]

The packf command compresses the messages in a folder into a specified file. By default, the packf command compresses messages from the current folder and places them in the msgbox file. If the file does not exist, the system prompts you for permission to create it. Each message in the file is separated with four Ctrl-A characters and a new-line character.

Note: You can use the inc command to unpack compressed messages.

Flags

-file File	Specifies the file in which to put compressed messages. The default is the ./msgbox file. If the file exists, the packf command appends the messages to the end of the file. Otherwise, the system prompts you for permission to create the file.
+Folder	Identifies the folder containing the messages you want to pack.
-help	Lists the command syntax, available switches (toggles), and version information. Note: For Message Handler (MH), the name of this flag must be fully spelled out.
Messages	Specifies what messages to pack. The Messages parameter can specify several messages, a range of messages, or a single message. If several messages are specified, the first message packed becomes the current message. Use the following references to specify messages: *Number* Number of the message. When specifying several messages, separate each number with a comma. When specifying a range, separate the first and last numbers in the range with a hyphen. *Sequence* A group of messages specified by the user. Recognized values include: all All the messages in the folder. This is the default. cur or . (period) Current message. first First message in a folder. last Last message in a folder. next Message immediately after the current message. prev Message immediately before the current message.
