burst - explode digests into messages (only available within the message handling system, mh)
burst [+folder] [msgs] [options]
Expands the forwarded message or digest in its current place in the folder. The message that is expanded is replaced by the header used to forward the message, or if it is a digest, by the table of contents. The burst command then places the extracted messages immediately after this, and re-numbers the rest of the messages in the folder to make room for them. The original message or digest is not saved.
The default settings for this command are:
+folder defaults to the current folder msgs defaults to the current message -noinplace -noquiet -noverbose
The burst command extracts the original messages from a forwarded message, discards the forwarder's header details, and places the original messages at the end of the current folder.
By default, burst takes the current message in the current folder. You can specify messages other than the current message by using burst with the +folder and msgs arguments. If you specify another message, that message becomes the current message. If you specify another folder, that folder becomes the current folder.
The burst command will expand either a single message which contains a number of separate messages packed together for ease of mailing, or an Internet digest. The packf and forw commands can both pack individual messages into a single message or file.
You can use
in combination with
to re-direct or forward mail more conveniently.
For example, if you wanted to forward a number of messages to yourself on
another account, you could use
to combine them and
send them in a single message. When the message arrives, you can use
to expand the single message into its constituent messages.
The burst program enforces a limit on the number of messages which may be expanded from a single message. This number is about 1000 messages. However, there is usually no limit on the number of messages which may reside in the folder after the messages have been expanded.
The burst command only works on messages that have been encapsulated according to the guidelines laid down by the proposed standard RFC 934. The encapsulated message is considered to start after burst encounters a line of dashes. If you attempt to use burst on a message that has not been encapsulated according to RFC 934, the results may be unpredictable. For example, burst may find an encapsulation boundary prematurely, and split a single encapsulated message into two or more messages.
Any text which appears after the last encapsulated message is not placed
in a separate message by
burst. When the
option is used, this trailing information is lost. Text which appears
before the first encapsulated message is not lost.
