 8.6 `mysqlaccess' -- Client for Checking Access Privileges
 ==========================================================
 
 `mysqlaccess' is a diagnostic tool that Yves Carlier has provided for
 the MySQL distribution. It checks the access privileges for a hostname,
 username, 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' understands 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 hostname to use in the access privileges.
 
    * -howto
 
      Display some examples that show how to use `mysqlaccess'.
 
    * -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.
 
    * -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, you are prompted for one.
 
      Specifying a password on the command line should be considered
      insecure. See  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 MySQL 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 -password
      or -p option on the command line, you are prompted for one.
 
      Specifying a password on the command line should be considered
      insecure. See  password-security.
 
    * -superuser=USER_NAME, -U USER_NAME
 
      Specify the username for connecting as the superuser.
 
    * -table, -t
 
      Generate reports in table format.
 
    * -user=USER_NAME, -u USER_NAME
 
      The username to use in the access privileges.
 
    * -version, -v
 
      Display version information and exit.
 
 If your MySQL 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'.
