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

        [-d|--debuglevel=DEBUGLEVEL] [--debug-stdout] [--configfile=CONFIGFILE]

       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

       The following database operations are available:

              •   fetch: fetch a record

              •   store: create or modify a record

              •   delete: remove a record

              •   exists: test for existence of a record

              •   erase: remove all records

              •   listkeys: list all available records

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

       The following types are available:

              •   int32: signed 32bit integer

              •   uint32: unsigned 32bit integer

              •   string: "hello world"

              •   hex: hex strings like "68656C6C6F20776F726C6400" ("hello world")


           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.

           Print a summary of command line options.

           Display brief usage message.

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

           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.

           This will redirect debug output to STDOUT. By default all clients are logging to

       --configfile=<configuration file>
           The file specified contains the configuration details required by the client. The
           information in this file can be general for client and server or only provide client
           specific like options such as client smb encrypt. See smb.conf for more information.
           The default configuration file name is determined at compile time.

           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. If a name
           or a value includes a space, wrap whole --option=name=value into quotes.

           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.

           Enable talloc leak reporting on exit.

           Enable full talloc leak reporting on exit.

           Prints the program version number.
