     mysqlaccess - client for checking access privileges

     mysqlaccess [host_name [user_name [db_name]]] [options]

     mysqlaccess is a diagnostic tool that Yves Carlier has
     provided for the MySQL distribution. 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.

     o   --help, -?

         Display a help message and exit.

     o   --brief, -b

         Generate reports in single-line tabular format.

     o   --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.)

     o   --copy

         Reload the temporary grant tables from original ones.

     o   --db=db_name, -d db_name

         Specify the database name.

     o   --debug=N

         Specify the debug level.  N can be an integer from 0 to

     o   --host=host_name, -h host_name

         The host name to use in the access privileges.

MySQL Database System                              MYSQLACCESS(1)

     o   --howto

         Display some examples that show how to use mysqlaccess.

     o   --old_server

         Assume that the server is an old MySQL server (before
         MySQL 3.21) that does not yet know how to handle full
         WHERE clauses.

     o   --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

         Specifying a password on the command line should be
         considered insecure. See Section, "End-User
         Guidelines for Password Security".

     o   --plan

         Display suggestions and ideas for future releases.

     o   --preview

         Show the privilege differences after making changes to
         the temporary grant tables.

     o   --relnotes

         Display the release notes.

     o   --rhost=host_name, -H host_name

         Connect to the MySQL server on the given host.

     o   --rollback

         Undo the most recent changes to the temporary grant

     o   --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, "End-User

         Guidelines for Password Security".

     o   --superuser=user_name, -U user_name

         Specify the user name for connecting as the superuser.

     o   --table, -t

         Generate reports in table format.

     o   --user=user_name, -u user_name

         The user name to use in the access privileges.

     o   --version, -v

         Display version information and exit.

     If your MySQL distribution is installed in some nonstandard
     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.
