       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 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.exclude_tags 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.
