NAME

       myisamlog - display MyISAM log file contents

SYNOPSIS

       myisamlog [options] [log_file [tbl_name] ...]

DESCRIPTION

       myisamlog processes the contents of a MyISAM log file. To create such a file, start the
       server with a --log-isam=log_file option.

       Invoke myisamlog like this:

           myisamlog [options] [file_name [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 if no log_file argument is given. If tables are named on the command line, only
       those tables are updated.
