=============
notmuch-count
=============
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 :any:`notmuch-search-terms(7)` for details of the supported syntax for
<search-terms>.
Supported options for **count** include
.. program:: count
.. option:: --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).
.. option:: --exclude=(true|false)
Specify whether to omit messages matching search.exclude\_tags from
the count (the default) or not.
.. option:: --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.
.. option:: --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.
.. option:: --input=<filename>
Read input from given file, instead of from stdin. Implies
``--batch``.
