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:

           shell> 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.

       myisamlog supports the following options:

       o   -?, -I

           Display a help message and exit.

       o   -c N

           Execute only N commands.

       o   -F filepath/

           Specify the starting offset.

       o   -p N

           Remove N components from path.
