DESCRIPTION

The command ‘kcpolymgr’ is a utility for test and debugging of the polymorphic database and its applications. ‘path’ specifies the path of a database file. ‘key’ specifies the key of a record. ‘value’ specifies the value of a record. ‘file’ specifies the input/output file. ‘src’ specifies other database files.

kcpolymgr create [−otr] [−onl|−otl|−onr] path

Creates a database file.

kcpolymgr inform [−onl|−otl|−onr] [−st] path

Prints status information.

kcpolymgr set [−onl|−otl|−onr] [−add|−app|−rep|−inci|−incd] [−sx] path key value

Stores a record.

kcpolymgr remove [−onl|−otl|−onr] [−sx] path key

Removes a record.

kcpolymgr get [−onl|−otl|−onr] [−rm] [−sx] [−px] [−pz] path key

Prints the value of a record.

kcpolymgr list [−onl|−otl|−onr] [−mp|−mr|−ms] [−des] [−max num] [−rm] [−sx] [−pv] [−px] path [key]

Prints keys of all records, separated by line feeds.

kcpolymgr clear [−onl|−otl|−onr] path

Removes all records of a database.

kcpolymgr import [−onl|−otl|−onr] [−sx] path [file]

Imports records from a TSV file.

kcpolymgr copy [−onl|−otl|−onr] path file

Copies the whole database.

kcpolymgr dump [−onl|−otl|−onr] path [file]

Dumps records into a snapshot file.

kcpolymgr load [−otr] [−onl|−otl|−onr] path [file]

Loads records from a snapshot file.

kcpolymgr merge [−onl|−otl|−onr] [−add|−app|−rep] path src...

Merge records from other databases.

kcpolymgr setbulk [−onl|−otl|−onr] path key value ...

Store records at once.

kcpolymgr removebulk [−onl|−otl|−onr] [−sx] path key ...

Remove records at once.

kcpolymgr getbulk [−onl|−otl|−onr] [−sx] [−px] path key ...

Retrieve records at once.

kcpolymgr check [−onl|−otl|−onr] path

Checks consistency.

Options feature the following.

−otr : opens the database with the truncation option.
−onl
: opens the database with the no locking option.
−otl
: opens the database with the try locking option.
−onr
: opens the database with the no auto repair option.
−st
: prints miscellaneous information.
−add
: performs adding operation.
−app
: performs appending operation.
−rep
: performs replacing operation.
−inci
: performs integer increment operation.
−incd
: performs real number increment operation.
−sx
: the input data is evaluated as a hexadecimal data string.
−rm
: removes the record.
−px
: the output data is converted into a hexadecimal data string.
−pz
: performs not append line feed at the end of the output.
−mp
: performs prefix matching instead of usual scan.
−mr
: performs regular expression matching instead of usual scan.
−ms
: performs similar matching instead of usual scan.
−des
: visits records in descending order.
−max
num : specifies the maximum number of shown records.
−pv
: prints values of records also.
