mysqlaccess is a diagnostic tool written by Yves Carlier. It
       checks the access privileges for a host name, user name, and
       database combination. Note that mysqlaccess checks access using
       only the user, db, and host tables. It does not check table,
       column, or routine privileges specified in the tables_priv,
       columns_priv, or procs_priv tables.
       Invoke mysqlaccess like this:
           shell> mysqlaccess [host_name [user_name [db_name]]] [options]
       mysqlaccess supports the following options.
       •   --help, -?
           Display a help message and exit.
       •   --brief, -b
           Generate reports in single-line tabular format.
       •   --commit
           Copy the new access privileges from the temporary tables to
           the original grant tables. The grant tables must be flushed
           for the new privileges to take effect. (For example, execute
           a mysqladmin reload command.)
       •   --copy
           Reload the temporary grant tables from original ones.
       •   --db=db_name, -d db_name
           Specify the database name.
       •   --debug=N
           Specify the debug level.  N can be an integer from 0 to 3.
       •   --host=host_name, -h host_name
           The host name to use in the access privileges.
       •   --howto
           Display some examples that show how to use mysqlaccess.
       •   --old_server
           Connect to a very old MySQL server (before MySQL 3.21) that
           does not know how to handle full WHERE clauses.
       •   --password[=password], -p[password]
           The password to use when connecting to the server. If you
           omit the password value following the --password or -p option
           on the command line, mysqlaccess prompts for one.
           Specifying a password on the command line should be
           considered insecure. See Section 5.3.2.2, 'End-User
           Guidelines for Password Security'.
       •   --plan
           Display suggestions and ideas for future releases.
       •   --preview
           Show the privilege differences after making changes to the
           temporary grant tables.
       •   --relnotes
           Display the release notes.
       •   --rhost=host_name, -H host_name
           Connect to the MariaDB server on the given host.
       •   --rollback
           Undo the most recent changes to the temporary grant tables.
       •   --spassword[=password], -P[password]
           The password to use when connecting to the server as the
           superuser. If you omit the password value following the
           --spassword or -p option on the command line, mysqlaccess
           prompts for one.
           Specifying a password on the command line should be
           considered insecure. See Section 5.3.2.2, 'End-User
           Guidelines for Password Security'.
       •   --superuser=user_name, -U user_name
           Specify the user name for connecting as the superuser.
       •   --table, -t
           Generate reports in table format.
       •   --user=user_name, -u user_name
           The user name to use in the access privileges.
       •   --version, -v
           Display version information and exit.
       If your MariaDB distribution is installed in some non-standard
       location, you must change the location where mysqlaccess expects
       to find the mysql client. Edit the mysqlaccess script at
       approximately line 18. Search for a line that looks like this:
           $MYSQL     = ´/usr/local/bin/mysql´;    # path to mysql executable
       Change the path to reflect the location where mysql actually is
       stored on your system. If you do not do this, a Broken pipe error
       will occur when you run mysqlaccess.
