notmuch - thread-based email index, search, and tagging
notmuch [option ...] command [arg ...]
Notmuch is a command-line based program for indexing, searching, reading, and tagging large collections of email messages. This page describes how to get started using notmuch from the command line, and gives a brief overview of the commands available. For more information on e.g. notmuch show consult the notmuch-show(1) man page, also accessible via notmuch help show The quickest way to get started with Notmuch is to simply invoke the notmuch command with no arguments, which will interactively guide you through the process of indexing your mail.
While the command-line program notmuch provides powerful functionality, it does not provide the most convenient interface for that functionality. More sophisticated interfaces are expected to be built on top of either the command-line interface, or more likely, on top of the notmuch library interface. See https://notmuchmail.org for more about alternate interfaces to notmuch. The emacs-based interface to notmuch (available under emacs/ in the Notmuch source distribution) is probably the most widely used at this time.
Supported global options for notmuch include
--help [command-name]
Print a synopsis of available commands and exit. With an
optional command name, show the man page for that subcommand.
--version
Print the installed version of notmuch, and exit.
--config=FILE
Specify the configuration file to use. This overrides any
configuration file specified by ${NOTMUCH_CONFIG}.
--uuid=HEX
Enforce that the database UUID (a unique identifier which
persists until e.g. the database is compacted) is HEX; exit
with an error if it is not. This is useful to detect rollover
in modification counts on messages. You can find this UUID
using e.g. notmuch count --lastmod
All global options except --config can also be specified after the
command. For example, notmuch subcommand --uuid=HEX is equivalent to
notmuch --uuid=HEX subcommand.
SETUP
The notmuch setup command is used to configure Notmuch for first use,
(or to reconfigure it later).
The setup command will prompt for your full name, your primary email
address, any alternate email addresses you use, and the directory
containing your email archives. Your answers will be written to a
configuration file in ${NOTMUCH_CONFIG} (if set) or
${HOME}/.notmuch-config . This configuration file will be created with
descriptive comments, making it easy to edit by hand later to change
the configuration. Or you can run notmuch setup again to change the
configuration.
The mail directory you specify can contain any number of
sub-directories and should primarily contain only files with individual
email messages (eg. maildir or mh archives are perfect). If there are
other, non-email files (such as indexes maintained by other email
programs) then notmuch will do its best to detect those and ignore
them.
Mail storage that uses mbox format, (where one mbox file contains many
messages), will not work with notmuch. If that's how your mail is
currently stored, it is recommended you first convert it to maildir
format with a utility such as mb2md before running notmuch setup .
Invoking notmuch with no command argument will run setup if the setup
command has not previously been completed.
OTHER COMMANDS
Several of the notmuch commands accept search terms with a common
syntax. See notmuch-search-terms(7) for more details on the supported
syntax.
The search, show, address and count commands are used to query the
email database.
The reply command is useful for preparing a template for an email
reply.
The tag command is the only command available for manipulating database
contents.
The dump and restore commands can be used to create a textual dump of
email tags for backup purposes, and to restore from that dump.
The config command can be used to get or set settings in the notmuch
configuration file.
The following environment variables can be used to control the behavior
of notmuch.
NOTMUCH_CONFIG
Specifies the location of the notmuch configuration file.
Notmuch will use ${HOME}/.notmuch-config if this variable is not
set.
NOTMUCH_TALLOC_REPORT
Location to write a talloc memory usage report. See
talloc_enable_leak_report_full in talloc(3) for more
information.
NOTMUCH_DEBUG_QUERY
If set to a non-empty value, the notmuch library will print (to
stderr) Xapian queries it constructs.
