NAME
notmuch-show - show messages matching the given search terms
SYNOPSIS
notmuch show [option ...] <search-term> ...
DESCRIPTION
Shows all messages matching the search terms.
See 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
--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.
--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:

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.
--format-version=N
Use the specified structured output format version. This is intended for programs that invoke
notmuch(1) internally. If omitted, the latest supported version will be used.
--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.
--verify
Compute and report the validity of any MIME cryptographic signatures found in the selected
content (ie. "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.
--decrypt
Decrypt any MIME encrypted parts found in the selected content (ie. "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.
Decryption expects a functioning gpg-agent(1) to provide any needed credentials. Without one,
the decryption will fail.
Implies --verify.
--exclude=(true|false)
Specify whether to omit threads only matching search.tag_exclude 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.
--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 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.
--include-html
Include "text/html" parts as part of the output (currently only supported with --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 notmuch search command.
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.
