NAME

gdbm_load − re-create a GDBM database from a dump file.

SYNOPSIS

gdbm_load [−MUnr] [−b NUM] [−c NUM] [−m MODE] [−u NAME|UID[:NAME|GID]] [−−block−size=NUM] [−−cache−size=NUM] [−−mmap=NUM] [−−mode=MODE] [−−no−meta] [−−replace] [−−update] [−−user=NAME|UID[:NAME|GID]] FILE [DB_FILE]

gdbm_load [−Vh] [−−help] [−−usage] [−−version]

DESCRIPTION

Create a gdbm database file DB_FILE from the dump file FILE. If the FILE argument is not supplied, output the created database to the standard error.

If the input file is in ASCII dump format, the mode and ownership of the created database are restored from the information in the dump. This can be overridden using the command line options (see below).

OPTIONS

−b, −−block−size=NUM

Sets block size.

−c, −−cache−size=NUM

Sets cache size.

−M, −−mmap

Use memory mapping.

−m, −−mode=MODE

Set database file mode (octal number).

−n, −−no−meta

Do not attempt to restore database meta-data (mode and ownership).

−r, −−replace

Replace existing keys. This must be used together with the −U (−−update) option.

−U, −−update

Update an existing database. Key/value pairs from the dump file will be added to that database, without removing the existing keys. To overwrite keys that are duplicated in the dump file, use the −−replace option.

If the database does not exist, it will be created.

−u, −−user=NAME|UID[:NAME|GID]

Set file ownership.

−h, −−help

Print a short usage summary.

−−usage

Print a list of available options.

−V, −−version

Print program version
