SYNOPSIS
|
||
|
|
========
|
||
|
|
|
||
|
|
**notmuch** **dump** [--format=(batch-tag|sup)] [--] [--output=<*file*>] [--] [<*search-term*> ...]
|
||
|
|

|
DESCRIPTION
|
||
|
|
===========
|
||
|
|
|
||
|
|
Dump tags for messages matching the given search terms.
|
||
|
|
|
||
|
|
Output is to the given filename, if any, or to stdout.
|
||
|
|
|
||
|
|
These tags are the only data in the notmuch database that can't be
|
||
|
|
recreated from the messages themselves. The output of notmuch dump is
|
||
|
|
therefore the only critical thing to backup (and much more friendly to
|
||
|
|
incremental backup than the native database files.)
|
||
|
|
|
||
|
|
``--format=(sup|batch-tag)``
|
||
|
|
Notmuch restore supports two plain text dump formats, both with one
|
||
|
|
message-id per line, followed by a list of tags.
|
||
|
|
|
||
|
|
**batch-tag**
|
||
|
|
The default **batch-tag** dump format is intended to more robust
|
||
|
|
against malformed message-ids and tags containing whitespace or
|
||
|
|
non-\ **ascii(7)** characters. Each line has the form
|
||
|
|
|
||
|
|
+<*encoded-tag*\ > +<*encoded-tag*\ > ... --
|
||
|
|
id:<*quoted-message-id*\ >
|
||
|
|
|
||
|
|
Tags are hex-encoded by replacing every byte not matching the
|
||
|
|
regex **[A-Za-z0-9@=.,\_+-]** with **%nn** where nn is the two
|
||
|
|
digit hex encoding. The message ID is a valid Xapian query,
|
||
|
|
quoted using Xapian boolean term quoting rules: if the ID
|
||
|
|
contains whitespace or a close paren or starts with a double
|
||
|
|
quote, it must be enclosed in double quotes and double quotes
|
||
|
|
inside the ID must be doubled. The astute reader will notice
|
||
|
|
this is a special case of the batch input format for
|
||
|
|
**notmuch-tag(1)**; note that the single message-id query is
|
||
|
|
mandatory for **notmuch-restore(1)**.
|
||
|
|
|
||
|
|
**sup**
|
||
|
|
The **sup** dump file format is specifically chosen to be
|
||
|
|
compatible with the format of files produced by sup-dump. So if
|
||
|
|
you've previously been using sup for mail, then the **notmuch
|
||
|
|
restore** command provides you a way to import all of your tags
|
||
|
|
(or labels as sup calls them). Each line has the following form
|
||
|
|
|
||
|
|
<*message-id*\ > **(** <*tag*\ > ... **)**
|
||
|
|
|
||
|
|
with zero or more tags are separated by spaces. Note that
|
||
|
|
(malformed) message-ids may contain arbitrary non-null
|
||
|
|
characters. Note also that tags with spaces will not be
|
||
|
|
correctly restored with this format.
|
||
|
|
|
||
|
|
With no search terms, a dump of all messages in the database will be
|
||
|
|
generated. A "--" argument instructs notmuch that the remaining
|
||
|
|
arguments are search terms.
|
||
|
|
|
||
|
|
See **notmuch-search-terms(7)** for details of the supported syntax
|
||
|
|
for <search-terms>.
