In the short term we need a way to get lastmod information e.g. for the test suite. In the long term we probably want to add lastmod information to at least the structured output for several other clients (e.g. show, search).

SYNOPSIS
|
|
========
|
|
|
|
**notmuch** **count** [*option* ...] <*search-term*> ...
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
Count messages matching the search terms.
|
|
|
|
The number of matching messages (or threads) is output to stdout.
|
|
|
|
With no search terms, a count of all messages (or threads) in the
|
|
database will be displayed.
|
|
|
|
See **notmuch-search-terms(7)** for details of the supported syntax for
|
|
<search-terms>.
|
|
|
|
Supported options for **count** include
|
|
|
|
``--output=(messages|threads|files)``
|
|
|
|
**messages**
|
|
Output the number of matching messages. This is the default.
|
|
|
|
**threads**
|
|
Output the number of matching threads.
|
|
|
|
**files**
|
|
Output the number of files associated with matching
|
|
messages. This may be bigger than the number of matching
|
|
messages due to duplicates (i.e. multiple files having the
|
|
same message-id).
|
|
|
|
``--exclude=(true|false)``
|
|
Specify whether to omit messages matching search.tag\_exclude
|
|
from the count (the default) or not.
|
|
|
|
``--batch``
|
|
Read queries from a file (stdin by default), one per line, and
|
|
output the number of matching messages (or threads) to stdout,
|
|
one per line. On an empty input line the count of all messages
|
|
(or threads) in the database will be output. This option is not
|
|
compatible with specifying search terms on the command line.
|
|
|
|
``--lastmod``
|
|
Append lastmod (counter for number of database updates) and UUID
|
|
to the output. lastmod values are only comparable between databases
|
|
with the same UUID.
|
|
|
|
``--input=``\ <filename>
|
|
Read input from given file, instead of from stdin. Implies
|
|
``--batch``.
