## NAME

cyr_dbtool - Cyrus IMAP documentation

Manage Cyrus databases

## SYNOPSIS

cyr_dbtool [ -C config-file ] [ -M ] [ -n ] [ -o ] [ -T ]
db-file db-backend action [ key ] [ value ]

## DESCRIPTION

cyr_dbtool is used to manage a cyrusdb file. The usable actions are:

show [<prefix>]

get <key>

set <key> <value>

delete <key>

consistency

repack

You may omit key or key/value and specify one per line on stdin. Keys are terminated by tab or newline, values are terminated by newline.

Running without any options will list the available database backends and usable actions.

The consistency action runs a consistency check on the DB by calling 'myconsistent' on it.

The repack action will compress the database by removing stale data on backends which support it. It's a NOOP otherwise.

cyr_dbtool reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.

NOTE:

Note that the file locations are NOT read out of the configuration file, and must be supplied on the command line.

TIP:

The format of all Cyrus databases is detailed in the distribution in file doc/internal/database-formats.html. Please consult that for details.

## OPTIONS

-C config-file

Use the specified configuration file config-file rather than the default imapd.conf(5).

| -M |  | Uses improved MBOX list sort
| -n |  | Create the database file if it doesn't already exist.
| -o |  | Store all the output in memory and only print it once the transaction is completed.
| -T |  | Use a transaction to do the action (most especially for 'show') - the default used to be transactions.

## EXAMPLES

This series of examples address manipulating the user_deny.db database, which is used to deny users access to specific services. This is typically a Cyrus "flat" format database.

user_deny.db is indexed by userid and each record contains the database version number (currently 2), a list of "wildmat" patterns specifying Cyrus services to be denied, and a text message to be displayed to the user upon denial. The service names to be matched are those as used in cyrus.conf(5). cyr_deny(8) provides more convenient way to manage user_deny.db.

NOTE:

Given that keys are tab-delimited, these examples use the notation <tab> to indicate the tab character. When entering this via the command line, remember to escape tabs. In a normal shell, one can do so with <ctrl-v> (^v). The sequence "<ctrl-v><ctrl-i>" (^v^i) works well to enter tab characters.

cyr_dbtool /var/lib/imap/user_deny.db flat baduser "2<tab>pop3,imap<tab>Denied"

Deny the user 'baduser' access to imap and pop3.

cyr_dbtool /var/lib/imap/user_deny.db flat show

Show all current database records.

cyr_dbtool /var/lib/imap/user_deny.db flat get baduser

Get the current database record(s) for user 'baduser'.
