db_printlog(1)            BSD General Commands Manual           db_printlog(1)

NAME
     db_printlog

SYNOPSIS
     db_printlog [-NrV] [-h home] [-P password]

DESCRIPTION
     The db_printlog utility is a debugging utility that dumps Berkeley DB log files in a human-readable
     format.

     The options are as follows:

     -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
        Read the log files in reverse order.

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

     For more information on the db_printlog output and using it to debug applications, see Reviewing Berke-ley Berkeley
     ley DB log files.

     The db_printlog utility uses 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, db_printlog should
     always be given the chance to detach from the environment and exit gracefully. To cause db_printlog to
     release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).

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

ENVIRONMENT
     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.
