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:
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.

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
${prefix}/etc/smb.conf
file.
This will redirect debug output to STDOUT. By default all clients are logging to STDERR.
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
${prefix}/etc/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.
