 8.11 `mysqlshow', Showing Databases, Tables, and Columns
 ========================================================
 
 The `mysqlshow' client can be used to quickly look at which databases
 exist, their tables, and a table's columns or indexes.
 
 `mysqlshow' provides a command-line interface to several SQL `SHOW'
 statements.  The same information can be obtained by using those
 statements directly.  For example, you can issue them from the `mysql'
 client program.   `SHOW' SHOW.
 
 Invoke `mysqlshow' like this:
 
      shell> mysqlshow [OPTIONS] [DB_NAME [TBL_NAME [COL_NAME]]]
 
    * If no database is given, all matching databases are shown.
 
    * If no table is given, all matching tables in the database are
      shown.
 
    * If no column is given, all matching columns and column types in
      the table are shown.
 
 Note that in newer MySQL versions, you see only those database, tables,
 or columns for which you have some privileges.
 
 If the last argument contains shell or SQL wildcard characters (`*',
 `?', `%', or `_'), only those names that are matched by the wildcard
 are shown.  If a database name contains any underscores, those should
 be escaped with a backslash (some Unix shells will require two) in
 order to get a list of the proper tables or columns. `*' and `?'
 characters are converted into SQL `%' and `_' wildcard characters.
 This might cause some confusion when you try to display the columns for
 a table with a `_' in the name, because in this case `mysqlshow' shows
 you only the table names that match the pattern.  This is easily fixed
 by adding an extra `%' last on the command line as a separate argument.
 
 `mysqlshow' supports the following options:
 
 `--help, -?'
      Display a help message and exit.
 
 `--character-sets-dir=PATH'
      The directory where character sets are installed.   Character
      sets.
 
 `--compress, -C'
      Compress all information sent between the client and the server if
      both support compression.
 
 `--debug[=DEBUG_OPTIONS], -# [DEBUG_OPTIONS]'
      Write a debugging log. The DEBUG_OPTIONS string often is
      `'d:t:o,FILE_NAME''.
 
 `--default-character-set=CHARSET'
      Use CHARSET as the default character set.   Character sets.
 
 `--host=HOST_NAME, -h HOST_NAME'
      Connect to the MySQL server on the given host.
 
 `--keys, -k'
      Show table indexes.
 
 `--password[=PASSWORD], -p[PASSWORD]'
      The password to use when connecting to the server.  If you use the
      short option form (`-p'), you _cannot_ have a space between the
      option and the password.  If you omit the PASSWORD value following
      the `--password' or `-p' option on the command line, you will be
      prompted for one.
 
 `--port=PORT_NUM, -P PORT_NUM'
      The TCP/IP port number to use for the connection.
 
 `--protocol={TCP | SOCKET | PIPE | MEMORY}'
      The connection protocol to use.  New in MySQL 4.1.
 
 `--socket=PATH, -S PATH'
      The socket file to use when connecting to `localhost' (which is the
      default host).
 
 `--status, -i'
      Display extra information about each table.
 
 `--user=USER_NAME, -u USER_NAME'
      The MySQL username to use when connecting to the server.
 
 `--verbose, -v'
      Verbose mode.  Print out more information what the program does.
      This option can be used multiple times to increase the amount of
      information.
 
 `--version, -V'
      Display version information and exit.
