    dbxml_dump [-NRrV] [-f output] [-h home] [-P password] file

### Description

The dbxml_dump utility reads the XML container in file file and writes it to the standard output using a portable flat-text format understood by the dbxml_load utility. The argument file must be a file produced using the Berkeley DB library functions.

The options are as follows:

-f
  Write to the specified file instead of to the standard output.

-h
  Specify a home directory for the database environment; by default, the current working directory is used.

-N
  Do not acquire shared region mutexes while running. Other problems, such as potentially fatal errors in Berkeley DB, will be ignored as well. This option is intended only for debugging errors, and should not be used under any other circumstances.

-P
  Specify an environment password. Although Berkeley DB utilities overwrite password strings as soon as possible, be aware there may be a window of vulnerability on systems where unprivileged users can see command-line arguments or where utilities are not able to overwrite the memory containing the command-line arguments.

-R
  Aggressively salvage data from a possibly corrupt file. The -R flag differs from the -r option in that it will return all possible data from the file at the risk of also returning already deleted or otherwise nonsensical items. Data dumped in this fashion will almost certainly have to be edited by hand or other means before the data is ready for reload into another XML container

-r
  Salvage data from a possibly corrupt file. When used on a uncorrupted XML container, this option should return equivalent data to a normal dump, but most likely in a different order.

-V
  Write the library version number to the standard output, and exit.

The dbxml_dump utility may be used with a Berkeley DB environment (as described for the -h option, the environment variable DB_HOME, or because the utility was run in a directory containing a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, dbxml_dump should always be given the chance to detach from the environment and exit gracefully. To cause dbxml_dump to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).

Even when using a Berkeley DB database environment, the dbxml_dump utility does not use any kind of database locking if it is invoked with the -R or -r arguments. If used with one of these arguments, the dbxml_dump utility may only be safely run on XML containers that are not being modified by any other process; otherwise, the output may be corrupt.

The dbxml_dump utility exits 0 on success, and >0 if an error occurs.

### Environment Variables

DB_HOME
  If the -h option is not specified and the environment variable DB_HOME is set, it is used as the path of the database home, as described in DB_ENV->open.
