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.
If -noinplace is given, the original message or digest is preserved.
The messages which burst extracts are placed at the end of the folder.
Other messages are not re-numbered. This is the default behavior.
Directs burst to be silent about reporting messages that are not in
digest format. Normally, an error message is printed if you attempt to
use burst on a message which does not contain encapsulated messages.
Reports the general actions that burst is taking to explode the digest.
The default settings for this command are:
+folder defaults to the current folder
msgs defaults to the current message
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 burst in combination with forw or packf 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 forw to combine them
and send them in a single message. When the message arrives, you can use
burst 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 -inplace option is used, this
trailing information is lost. Text which appears before the first
encapsulated message is not lost.
