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. The default log file name is myisam.log for myisamlog and isam.log for isamlog if no log_file argument is given. If tables are named on the command line, only those tables are updated.
