Synopsis: %(prog)s [-h|-g|-b|-r|-a] dbfile [ picklefile ]
|
|
|
|
Convert the database file given on the command line to a pickle
|
|
representation. The optional flags indicate the type of the database:
|
|
|
|
-a - open using anydbm
|
|
-b - open as bsddb btree file
|
|
-d - open as dbm file
|
|
-g - open as gdbm file
|
|
-h - open as bsddb hash file
|
|
-r - open as bsddb recno file
|
|
|
|
The default is hash. If a pickle file is named it is opened for write
|
|
access (deleting any existing data). If no pickle file is named, the pickle
|
|
output is written to standard output.
