       dbwrap_tool - low level TDB/CTDB manipulation tool using the dbwrap

       dbwrap_tool [--persistent] [--non-persistent] [-d <debug level>]
        [-s <config file>] [-l <log file base>] [-V] [--option=<name>=<value>]
        {<database>} {<operation>} [<key> [<type> [<value>]]]

       This tool is part of the samba(7) suite.

       The dbwrap_tool program is used to read and manipulate TDB/CTDB
       databases using the dbwrap interface.

       The following database operations are available:

              o   fetch: fetch a record

              o   store: create or modify a record

              o   delete: remove a record

              o   exists: test for existence of a record

              o   erase: remove all records

              o   listkeys: list all available records

              o   listwatchers: list processes, which are waiting for changes
                  in a record

       The following types are available:

              o   int32: signed 32bit integer

              o   uint32: unsigned 32bit integer

              o   string: "hello world"

              o   hex: hex strings like "68656C6C6F20776F726C6400" ("hello

           Open the database as a persistent database.

           Exactly one of --persistent and --non-persistent must be specified.

           Open the database as a non-persistent database.

           Caveat: opening a database as non-persistent when there is
           currently no other opener will wipe the database.

           Exactly one of --persistent and --non-persistent must be specified.

           level is an integer from 0 to 10. The default value if this
           parameter is not specified is 1.

           The higher this value, the more detail will be logged to the log
           files about the activities of the server. At level 0, only critical
           errors and serious warnings will be logged. Level 1 is a reasonable
           level for day-to-day running - it generates a small amount of
           information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and
           should only be used when investigating a problem. Levels above 3
           are designed for use only by developers and generate HUGE amounts
           of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log
           level parameter in the smb.conf file.

           Prints the program version number.

       -s|--configfile=<configuration file>
           The file specified contains the configuration details required by
           the server. The information in this file includes server-specific
           information such as what printcap file to use, as well as
           descriptions of all the services that the server is to provide. See
           smb.conf for more information. The default configuration file name
           is determined at compile time.

           Base directory name for log/debug files. The extension ".progname"
           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
           file is never removed by the client.

           Set the smb.conf(5) option "<name>" to value "<value>" from the
           command line. This overrides compiled-in defaults and options read
           from the configuration file.

           Print a summary of command line options.

       This man page is correct for version 3 of the Samba suite.

       smbd(8), samba(7)

       The original Samba software and related utilities were created by
       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The dbwrap_tool manpage was written by Bjoern Baumbach.
