NAME
       mysqlshow - display database, table, and column information

SYNOPSIS
       mysqlshow [options] [db_name [tbl_name [col_name]]]

DESCRIPTION
       The mysqlshow client can be used to quickly see which databases exist, their tables, or a
       table's columns or indexes.

       mysqlshow provides a command-line interface to several SQL SHOW statements. See
       Section 12.4.5, "SHOW Syntax". The same information can be obtained by using those
       statements directly. For example, you can issue them from the mysql client program.

       Invoke mysqlshow like this:

	   shell> mysqlshow [options] [db_name [tbl_name [col_name]]]

       o   If no database is given, a list of database names is shown.

       o   If no table is given, all matching tables in the database are shown.

       o   If no column is given, all matching columns and column types in the table are shown.

       The output displays only the names of those databases, 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 require two)
       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, which can be specified on the command line or in
       the [mysqlshow] and [client] option file groups.  mysqlshow also supports the options for
       processing option files described at Section 4.2.3.3.1, "Command-Line Options that Affect
       Option-File Handling".

       o   --help, -?

	   Display a help message and exit.

       o   --character-sets-dir=path, -c

	   The directory where character sets are installed. See Section 9.5, "Character Set
	   Configuration".

       o   --compress, -C

	   Compress all information sent between the client and the server if both support
	   compression.

       o   --count

	   Show the number of rows per table. This can be slow for non-MyISAM tables.

       o   --debug[=debug_options], -# [debug_options]

	   Write a debugging log. A typical debug_options string is 'd:t:o,file_name'. The
	   default is 'd:t:o'.

       o   --debug-check

	   Print some debugging information when the program exits. This option was added in
	   MySQL 5.1.21.

       o   --debug-info

	   Print debugging information and memory and CPU usage statistics when the program
	   exits. This option was added in MySQL 5.1.14.

       o   --default-character-set=charset_name

	   Use charset_name as the default character set. See Section 9.5, "Character Set
	   Configuration".

       o   --defaults-extra-file=filename

	   Set filename as the file to read default options from after the global defaults files
	   has been read.  Must be given as first option.

       o   --defaults-file=filename

	   Set filename as the file to read default options from, override global defaults files.
	   Must be given as first option.

       o   --host=host_name, -h host_name

	   Connect to the MySQL server on the given host.

       o   --keys, -k

	   Show table indexes.

       o   --no-defaults

	   Do not read default options from any option file. This must be given as the first
	   argument.

       o   --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, mysqlshow
	   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". You can use an option
	   file to avoid giving the password on the command line.

       o   --pipe, -W

	   On Windows, connect to the server via a named pipe. This option applies only if the
	   server supports named-pipe connections.

       o   --port=port_num, -P port_num

	   The TCP/IP port number to use for the connection.

       o   --protocol={TCP|SOCKET|PIPE|MEMORY}

	   The connection protocol to use for connecting to the server. It is useful when the
	   other connection parameters normally would cause a protocol to be used other than the
	   one you want. For details on the allowable values, see Section 4.2.2, "Connecting to
	   the MySQL Server".

       o   --print-defaults

	   Print the program argument list and exit.  This must be given as the first argument.

       o   --show-table-type, -t

	   Show a column indicating the table type, as in SHOW FULL TABLES. The type is BASE
	   TABLE or VIEW.

       o   --socket=path, -S path

	   For connections to localhost, the Unix socket file to use, or, on Windows, the name of
	   the named pipe to use.

       o   --ssl*

	   Options that begin with --ssl specify whether to connect to the server via SSL and
	   indicate where to find SSL keys and certificates. See Section 5.5.6.3, "SSL Command
	   Options".

       o   --status, -i

	   Display extra information about each table.

       o   --user=user_name, -u user_name

	   The MySQL user name to use when connecting to the server.

       o   --verbose, -v

	   Verbose mode. Print more information about what the program does. This option can be
	   used multiple times to increase the amount of information.

       o   --version, -V

	   Display version information and exit.
