kchashmgr create [ -otr ] [ -onl | -otl | -onr ] [ -apow num ] [ -fpow num ] [ -ts ] [ -tl ] [ -tc ] [ -bnum num ] path

Creates a database file.

kchashmgr inform [ -onl | -otl | -onr ] [ -st ] path

Prints status information.

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

Stores a record.

kchashmgr remove [ -onl | -otl | -onr ] [ -sx ] path key

Removes a record.

kchashmgr get [ -onl | -otl | -onr ] [ -rm ] [ -sx ] [ -px ] [ -pz ] path key

Prints the value of a record.

kchashmgr list [ -onl | -otl | -onr ] [ -max num ] [ -rm ] [ -sx ] [ -pv ] [ -px ] path [ key ]

Prints keys of all records, separated by line feeds.

kchashmgr clear [ -onl | -otl | -onr ] path

Removes all records of a database.

kchashmgr import [ -onl | -otl | -onr ] [ -sx ] path [ file ]

Imports records from a TSV file.

kchashmgr copy [ -onl | -otl | -onr ] path file

Copies the whole database.

kchashmgr dump [ -onl | -otl | -onr ] path [ file ]

Dumps records into a snapshot file.

kchashmgr load [ -otr ] [ -onl | -otl | -onr ] path [ file ]

Loads records from a snapshot file.

kchashmgr defrag [ -onl | -otl | -onr ] path

Performs defragmentation.

kchashmgr setbulk [ -onl | -otl | -onr ] path key value ...

Store records at once.

kchashmgr removebulk [ -onl | -otl | -onr ] [ -sx ] path key ...

Remove records at once.

kchashmgr getbulk [ -onl | -otl | -onr ] [ -sx ] [ -px ] path key ...

Retrieve records at once.

kchashmgr 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.
-apow num : specifies the power of the alignment of record size.
-fpow num : specifies the power of the capacity of the free block pool.
-ts : tunes the database with the small option.
-tl : tunes the database with the linear option.
-tc : tunes the database with the compression option.
-bnum num : specifies the number of buckets of the hash table.
-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 : does not append line feed at the end of the output.
-max num : specifies the maximum number of shown records.
