myisamlog
myisamlog processes and returns the contents of a MyISAM log file.
Invoke myisamlog like this:
shell> myisamlog [options] [log_file [tbl_name] ...] shell> isamlog [options] [log_file [tbl_name] ...]
The default operation is update (-u). If a recovery is done (-r), all writes and possibly updates and deletes are done and errors are only counted.
