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
