notmuch-count - count messages matching the given search terms
notmuch count [option ...]
<search-term> ...
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.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.
