The options described in this section can be used for any type of table maintenance operation
performed by myisamchk. The sections following this one describe options that pertain only to specific
operations, such as table checking or repairing.

General Options
Description
Skip rows larger than the given length if myisamchk
cannot allocate memory to hold them
Do a check that is faster than an --extend-check
operation
Block size to be used for MyISAM index pages
Uses the same technique as -r and -n, but creates all the
keys in parallel, using different threads (beta)
Achieve a faster repair by not modifying the data file.
Each thread that does a sequential scan allocates a
buffer of this size for each table it scans
Don't mark the table as checked
Do a repair that can fix almost any problem except unique
keys that aren't unique
Do a repair using an old recovery method that reads
through all rows in order and updates all index trees
based on the rows found
Force AUTO_INCREMENT numbering for new records to
start at the given value
Change the character set used by the table indexes
Specify the collation to use for sorting table indexes
Silent mode
The buffer that is allocated when sorting the index when
doing a REPAIR or when creating indexes with CREATE
INDEX or ALTER TABLE
Sort the index tree blocks in high-low order
sort_key_blocks
Sort records according to a particular index
Force myisamchk to use sorting to resolve the keys even
if the temporary files would be very large
Specifies how MyISAM index statistics collection code
should treat NULLs
Path of the directory to be used for storing temporary files
Unpack a table that was packed with myisampack
Store information in the .MYI file to indicate when the
table was checked and whether the table crashed
Verbose mode
Display version information and exit
Write buffer size
