SYNOPSIS
|
|
========
|
|
|
|
**notmuch** **show** [*option* ...] <*search-term*> ...
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
Shows all messages matching the search terms.
|
|
|
|
See :any:`notmuch-search-terms(7)` for details of the supported syntax for
|
|
<search-terms>.
|
|
|
|
The messages will be grouped and sorted based on the threading (all
|
|
replies to a particular message will appear immediately after that
|
|
message in date order). The output is not indented by default, but depth
|
|
tags are printed so that proper indentation can be performed by a
|
|
post-processor (such as the emacs interface to notmuch).
|
|
|
|
Supported options for **show** include
|
|
|
|
.. program:: show
|
|
|
|
.. option:: --entire-thread=(true|false)
|
|
|
|
If true, **notmuch show** outputs all messages in the thread of
|
|
any message matching the search terms; if false, it outputs only
|
|
the matching messages. For ``--format=json`` and ``--format=sexp``
|
|
this defaults to true. For other formats, this defaults to false.
|
|
|
|
.. option:: --format=(text|json|sexp|mbox|raw)
|
|
|
|
text (default for messages)
|
|
The default plain-text format has all text-content MIME parts
|
|
decoded. Various components in the output, (**message**,
|
|
**header**, **body**, **attachment**, and MIME **part**), will
|
|
be delimited by easily-parsed markers. Each marker consists of
|
|
a Control-L character (ASCII decimal 12), the name of the
|
|
marker, and then either an opening or closing brace, ('{' or
|
|
'}'), to either open or close the component. For a multipart
|
|
MIME message, these parts will be nested.
|
|
|
|
json
|
|
The output is formatted with Javascript Object Notation
|
|
(JSON). This format is more robust than the text format for
|
|
automated processing. The nested structure of multipart MIME
|
|
messages is reflected in nested JSON output. By default JSON
|
|
output includes all messages in a matching thread; that is, by
|
|
default, ``--format=json`` sets ``--entire-thread``. The
|
|
caller can disable this behaviour by setting
|
|
``--entire-thread=false``. The JSON output is always encoded
|
|
as UTF-8 and any message content included in the output will
|
|
be charset-converted to UTF-8.
|
|
|
|
sexp
|
|
The output is formatted as the Lisp s-expression (sexp)
|
|
equivalent of the JSON format above. Objects are formatted as
|
|
property lists whose keys are keywords (symbols preceded by a
|
|
colon). True is formatted as ``t`` and both false and null are
|
|
formatted as ``nil``. As for JSON, the s-expression output is
|
|
always encoded as UTF-8.
|
|
|
|
mbox
|
|
All matching messages are output in the traditional, Unix mbox
|
|
format with each message being prefixed by a line beginning
|
|
with "From " and a blank line separating each message. Lines
|
|
in the message content beginning with "From " (preceded by
|
|
zero or more '>' characters) have an additional '>' character
|
|
added. This reversible escaping is termed "mboxrd" format and
|
|
described in detail here:
|
|
|
|
http://homepage.ntlworld.com/jonathan.deboynepollard/FGA/mail-mbox-formats.html
|
|
|
|
raw (default if ``--part`` is given)
|
|
Write the raw bytes of the given MIME part of a message to
|
|
standard out. For this format, it is an error to specify a
|
|
query that matches more than one message.
|
|
|
|
If the specified part is a leaf part, this outputs the body of
|
|
the part after performing content transfer decoding (but no
|
|
charset conversion). This is suitable for saving attachments,
|
|
for example.
|
|
|
|
For a multipart or message part, the output includes the part
|
|
headers as well as the body (including all child parts). No
|
|
decoding is performed because multipart and message parts
|
|
cannot have non-trivial content transfer encoding. Consumers
|
|
of this may need to implement MIME decoding and similar
|
|
functions.
|
|
|
|
.. option:: --format-version=N
|
|
|
|
Use the specified structured output format version. This is
|
|
intended for programs that invoke :any:`notmuch(1)` internally. If
|
|
omitted, the latest supported version will be used.
|
|
|
|
.. option:: --part=N
|
|
|
|
Output the single decoded MIME part N of a single message. The
|
|
search terms must match only a single message. Message parts are
|
|
numbered in a depth-first walk of the message MIME structure, and
|
|
are identified in the 'json', 'sexp' or 'text' output formats.
|
|
|
|
Note that even a message with no MIME structure or a single body
|
|
part still has two MIME parts: part 0 is the whole message
|
|
(headers and body) and part 1 is just the body.
|
|
|
|
.. option:: --sort=(newest-first|oldest-first)
|
|
|
|
This option can be used to present results in either chronological
|
|
order (**oldest-first**) or reverse chronological order
|
|
(**newest-first**).
|
|
|
|
Only threads as a whole are reordered. Ordering of messages within
|
|
each thread will not be affected by this flag, since that order is
|
|
always determined by the thread's replies.
|
|
|
|
By default, results will be displayed in reverse chronological
|
|
order, (that is, the newest results will be displayed first).
|
|
|
|
.. option:: --verify
|
|
|
|
Compute and report the validity of any MIME cryptographic
|
|
signatures found in the selected content (e.g., "multipart/signed"
|
|
parts). Status of the signature will be reported (currently only
|
|
supported with ``--format=json`` and ``--format=sexp``), and the
|
|
multipart/signed part will be replaced by the signed data.
|
|
|
|
.. option:: --decrypt=(false|auto|true|stash)
|
|
|
|
If ``true``, decrypt any MIME encrypted parts found in the
|
|
selected content (e.g., "multipart/encrypted" parts). Status of
|
|
the decryption will be reported (currently only supported
|
|
with ``--format=json`` and ``--format=sexp``) and on successful
|
|
decryption the multipart/encrypted part will be replaced by
|
|
the decrypted content.
|
|
|
|
``stash`` behaves like ``true``, but upon successful decryption it
|
|
will also stash the message's session key in the database, and
|
|
index the cleartext of the message, enabling automatic decryption
|
|
in the future.
|
|
|
|
If ``auto``, and a session key is already known for the
|
|
message, then it will be decrypted, but notmuch will not try
|
|
to access the user's keys.
|
|
|
|
Use ``false`` to avoid even automatic decryption.
|
|
|
|
Non-automatic decryption (``stash`` or ``true``, in the absence of
|
|
a stashed session key) expects a functioning :manpage:`gpg-agent(1)` to
|
|
provide any needed credentials. Without one, the decryption will
|
|
fail.
|
|
|
|
Note: setting either ``true`` or ``stash`` here implies
|
|
``--verify``.
|
|
|
|
Here is a table that summarizes each of these policies:
|
|
|
|
+------------------------+-------+------+------+-------+
|
|
| | false | auto | true | stash |
|
|
+========================+=======+======+======+=======+
|
|
| Show cleartext if | | X | X | X |
|
|
| session key is | | | | |
|
|
| already known | | | | |
|
|
+------------------------+-------+------+------+-------+
|
|
| Use secret keys to | | | X | X |
|
|
| show cleartext | | | | |
|
|
+------------------------+-------+------+------+-------+
|
|
| Stash any newly | | | | X |
|
|
| recovered session keys,| | | | |
|
|
| reindexing message if | | | | |
|
|
| found | | | | |
|
|
+------------------------+-------+------+------+-------+
|
|
|
|
Note: ``--decrypt=stash`` requires write access to the database.
|
|
Otherwise, ``notmuch show`` operates entirely in read-only mode.
|
|
|
|
Default: ``auto``
|
|
|
|
.. option:: --exclude=(true|false)
|
|
|
|
Specify whether to omit threads only matching search.exclude\_tags
|
|
from the search results (the default) or not. In either case the
|
|
excluded message will be marked with the exclude flag (except when
|
|
output=mbox when there is nowhere to put the flag).
|
|
|
|
If ``--entire-thread`` is specified then complete threads are returned
|
|
regardless (with the excluded flag being set when appropriate) but
|
|
threads that only match in an excluded message are not returned
|
|
when ``--exclude=true.``
|
|
|
|
The default is ``--exclude=true.``
|
|
|
|
.. option:: --body=(true|false)
|
|
|
|
If true (the default) **notmuch show** includes the bodies of the
|
|
messages in the output; if false, bodies are omitted.
|
|
``--body=false`` is only implemented for the text, json and sexp
|
|
formats and it is incompatible with ``--part > 0.``
|
|
|
|
This is useful if the caller only needs the headers as body-less
|
|
output is much faster and substantially smaller.
|
|
|
|
.. option:: --include-html
|
|
|
|
Include "text/html" parts as part of the output (currently
|
|
only supported with ``--format=text``, ``--format=json`` and
|
|
``--format=sexp``). By default, unless ``--part=N`` is used to
|
|
select a specific part or ``--include-html`` is used to include all
|
|
"text/html" parts, no part with content type "text/html" is included
|
|
in the output.
|
|
|
|
A common use of **notmuch show** is to display a single thread of
|
|
email messages. For this, use a search term of "thread:<thread-id>" as
|
|
can be seen in the first column of output from the
|
|
:any:`notmuch-search(1)` command.
|
|
|
|
CONFIGURATION
|
|
=============
|
|
|
|
Structured output (json / sexp) is influenced by the configuration
|
|
option :nmconfig:`show.extra_headers`. See
|
|
:any:`notmuch-config(1)` for details.
|
|
|
|
EXIT STATUS
|
|
===========
|
|
|
|
This command supports the following special exit status codes
|
|
|
|
``20``
|
|
The requested format version is too old.
|
|
|
|
``21``
|
|
The requested format version is too new.
