NAME

       notmuch-count - count messages matching the given search terms

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 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.
