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(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.
