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
-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 burst in combination with forw or packf to redirect
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.
