SYNOPSIS

9       myisamlog [options] [log_file [tbl_name] ...]
10

DESCRIPTION

12       myisamlog processes the contents of a MyISAM log file. To create such a
13       file, start the server with a --log-isam=log_file option.
14
15       Invoke myisamlog like this:
16
17           myisamlog [options] [file_name [tbl_name] ...]
18
19       The default operation is update (-u). If a recovery is done (-r), all
20       writes and possibly updates and deletes are done and errors are only
21       counted. The default log file name is myisam.log if no log_file
22       argument is given. If tables are named on the command line, only those
23       tables are updated.
