SYNOPSIS
|
|
========
|
|
|
|
**notmuch** **dump** [--gzip] [--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.)
|
|
|
|
See **notmuch-search-terms(7)** for details of the supported syntax
|
|
for <search-terms>. 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.
|
|
|
|
Supported options for **dump** include
|
|
|
|
``--gzip``
|
|
Compress the output in a format compatible with **gzip(1)**.
|
|
|
|
``--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.
|
|
|
|
``--output=``\ <filename>
|
|
Write output to given file instead of stdout.
