NOTMUCH-SETUP(1) notmuch NOTMUCH-SETUP(1) NAME notmuch-setup - getting started with notmuch SYNOPSIS notmuch [option ...] command [arg ...] DESCRIPTION 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 man page, also accessible via notmuch help show The quickest way to get started with Notmuch is to simply invoke the not- much command with no arguments, which will interactively guide you through the process of indexing your mail. NOTE 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 com- mand-line interface, or more likely, on top of the notmuch library inter- face. 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. OPTIONS 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 configura- tion file specified by NOTMUCH_CONFIG. The empty string is a permit- ted and sometimes useful value of FILE, which tells notmuch to use only configuration metadata from the database. --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 --last- mod 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. COMMANDS 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 ad- dress, 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 mes- sages), 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(1) before running notmuch setup. Invoking notmuch with no command argument will run setup if the setup com- mand has not previously been completed. OTHER COMMANDS Several of the notmuch commands accept search terms with a common syntax. See notmuch-search-terms for more details on the supported syntax. The notmuch-search, notmuch-show, notmuch-address and notmuch-count com- mands are used to query the email database. The notmuch-reply command is useful for preparing a template for an email reply. The notmuch-tag command is the only command available for manipulating database contents. The notmuch-dump and notmuch-restore commands can be used to create a tex- tual dump of email tags for backup purposes, and to restore from that dump. The notmuch-config command can be used to get or set settings in the not- much configuration file. EXTERNAL COMMANDS If the given command is not known to notmuch, notmuch tries to execute the external notmuch-<subcommand> in PATH instead. This allows users to have their own notmuch related tools to be run via the notmuch command. By de- sign, this does not allow notmuch's own commands to be overridden using ex- ternal commands. The environment variable NOTMUCH_CONFIG will be set ac- cording to --config, if the latter is present. OPTION SYNTAX All options accepting an argument can be used with '=' or ':' as a separa- tor. Except for boolean options (which would be ambiguous), a space can also be used as a separator. The following are all equivalent: notmuch --config=alt-config config get user.name notmuch --config:alt-config config get user.name notmuch --config alt-config config get user.name DUPLICATE MESSAGE FILES Notmuch considers the Message-ID to be the primary identifier of message. Per RFC 5322 the Message-ID is supposed to be globally unique, but this fails in two distinct ways. When you receive copies of a message via a mechanism like Cc or via a mailing list, the copies are typically inter- changeable. In the case of some broken mail sending software, the same Mes- sage-ID is used for completely unrelated messages. The options search --du- plicate and show --duplicate options provide the user with control over which message file is displayed. Front ends will need to provide their own interface, see e.g. the Emacs front-end emacs-show-duplicates. ENVIRONMENT The following environment variables can be used to control the behavior of notmuch. NOTMUCH_CONFIG Specifies the location of the notmuch configuration file. See notmuch-config for details. NOTMUCH_DATABASE Specifies the location of the notmuch database. See notmuch-config for details. NOTMUCH_PROFILE Selects among notmuch configurations. See notmuch-config for de- tails. NOTMUCH_TALLOC_REPORT Location to write a talloc memory usage report. See talloc_en- able_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.
