db_verify [-NqV] [-h home] file ...
The db_verify utility verifies the structure of one or more files and the databases they contain.
The options are as follows:
The db_verify utility does not perform any locking, even in Berkeley DB environments that are configured with a locking subsystem. As such, it should only be used on files that are not being modified by another thread of control.
If the file being verified contains databases using non-default comparison or hashing functions, the db_verify utility may not be used for verification, as it will likely always return failure. Such files must be verified explicitly, using the DB->verify function, after setting the correct comparison or hashing functions.
The db_verify 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, db_verify should always be given the chance to detach from the environment and exit gracefully. To cause db_verify to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).
The db_verify utility exits 0 on success, and >0 if an error occurs.
