kchashmgr - command line interface to manage the file hash database
The command `kchashmgr' is a utility for test and debugging of the file hash 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. 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. -pv : prints values of records also. This command returns 0 on success, another on failure.
