5 notmuch - thread-based email index, search, and tagging
10 <b>notmuch</b> [option ...] <b>command</b> [arg ...]
15 Notmuch is a command-line based program for indexing, searching, read‐
16 ing, and tagging large collections of email messages.
18 This page describes how to get started using notmuch from the command
19 line, and gives a brief overview of the commands available. For more
20 information on e.g. <b>notmuch</b> <b>show</b> consult the <a href='../notmuch-show-1/'>notmuch-show</a>(1) man page,
21 also accessible via <b>notmuch</b> <b>help</b> <b>show</b>
23 The quickest way to get started with Notmuch is to simply invoke the
24 <b>notmuch</b> command with no arguments, which will interactively guide you
25 through the process of indexing your mail.
30 While the command-line program <b>notmuch</b> provides powerful functionality,
31 it does not provide the most convenient interface for that functional‐
32 ity. More sophisticated interfaces are expected to be built on top of
33 either the command-line interface, or more likely, on top of the not‐
34 much library interface. See <u>https://notmuchmail.org</u> for more about
35 alternate interfaces to notmuch. The emacs-based interface to notmuch
36 (available under <b>emacs/</b> in the Notmuch source distribution) is probably
37 the most widely used at this time.
42 Supported global options for <b>notmuch</b> include
44 <b>--help</b> <b>[command-name]</b>
45 Print a synopsis of available commands and exit. With an
46 optional command name, show the man page for that subcommand.
49 Print the installed version of notmuch, and exit.
52 Specify the configuration file to use. This overrides any con‐
53 figuration file specified by ${NOTMUCH_CONFIG}.
56 Enforce that the database UUID (a unique identifier which per‐
57 sists until e.g. the database is compacted) is HEX; exit with an
58 error if it is not. This is useful to detect rollover in modifi‐
59 cation counts on messages. You can find this UUID using e.g.
60 <b>notmuch</b> <b>count</b> <b>--lastmod</b>
62 All global options except <b>--config</b> can also be specified after the com‐
63 mand. For example, <b>notmuch</b> <b>subcommand</b> <b>--uuid=HEX</b> is equivalent to <b>not-</b>
64 <b>much</b> <b>--uuid=HEX</b> <b>subcommand</b>.
69 <h3> SETUP</h3>
71 The <b>notmuch</b> <b>setup</b> command is used to configure Notmuch for first use,
72 (or to reconfigure it later).
74 The setup command will prompt for your full name, your primary email
75 address, any alternate email addresses you use, and the directory con‐
76 taining your email archives. Your answers will be written to a configu‐
77 ration file in ${NOTMUCH_CONFIG} (if set) or ${HOME}/.notmuch-config .
78 This configuration file will be created with descriptive comments, mak‐
79 ing it easy to edit by hand later to change the configuration. Or you
80 can run <b>notmuch</b> <b>setup</b> again to change the configuration.
82 The mail directory you specify can contain any number of sub-directo‐
83 ries and should primarily contain only files with individual email mes‐
84 sages (eg. maildir or mh archives are perfect). If there are other,
85 non-email files (such as indexes maintained by other email programs)
86 then notmuch will do its best to detect those and ignore them.
88 Mail storage that uses mbox format, (where one mbox file contains many
89 messages), will not work with notmuch. If that's how your mail is cur‐
90 rently stored, it is recommended you first convert it to maildir format
91 with a utility such as mb2md before running <b>notmuch</b> <b>setup</b> <b>.</b>
93 Invoking <b>notmuch</b> with no command argument will run <b>setup</b> if the setup
94 command has not previously been completed.
97 <h3> OTHER COMMANDS</h3>
99 Several of the notmuch commands accept search terms with a common syn‐
100 tax. See <b>notmuch-search-terms</b>(7) for more details on the supported syn‐
103 The <b>search</b>, <b>show</b>, <b>address</b> and <b>count</b> commands are used to query the
106 The <b>reply</b> command is useful for preparing a template for an email
109 The <b>tag</b> command is the only command available for manipulating database
112 The <b>dump</b> and <b>restore</b> commands can be used to create a textual dump of
113 email tags for backup purposes, and to restore from that dump.
115 The <b>config</b> command can be used to get or set settings in the notmuch
119 <h3> CUSTOM COMMANDS</h3>
121 If the given command is not known to notmuch, notmuch tries to execute
122 the external <b>notmuch-<subcommand></b> in ${PATH} instead. This allows users
123 to have their own notmuch related tools to be run via the notmuch com‐
124 mand. By design, this does not allow notmuch's own commands to be over‐
125 ridden using external commands.
128 <h3> OPTION SYNTAX</h3>
130 All options accepting an argument can be used with '=' or ':' as a sep‐
131 arator. Except for boolean options (which would be ambiguous), a space
132 can also be used as a separator. The following are all equivalent:
134 notmuch --config=alt-config config get user.name
135 notmuch --config:alt-config config get user.name
136 notmuch --config alt-config config get user.name
141 The following environment variables can be used to control the behavior
144 <b>NOTMUCH</b>_<b>CONFIG</b>
145 Specifies the location of the notmuch configuration file. Not‐
146 much will use ${HOME}/.notmuch-config if this variable is not
149 <b>NOTMUCH</b>_<b>TALLOC</b>_<b>REPORT</b>
150 Location to write a talloc memory usage report. See <b>tal-</b>
151 <b>loc</b>_<b>enable</b>_<b>leak</b>_<b>report</b>_<b>full</b> in <b>talloc</b>(3) for more information.
153 <b>NOTMUCH</b>_<b>DEBUG</b>_<b>QUERY</b>
154 If set to a non-empty value, the notmuch library will print (to
155 stderr) Xapian queries it constructs.
