       mysqlshow - display database, table, and	column information

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

       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 14.7.5, "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

       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] groups of an option
       file. For information about option files	used by	MySQL programs,	see
       Section 5.2.6, "Using Option Files".

       o   --help, -?

	   Display a help message and exit.

       o   --bind-address=ip_address

	   On a	computer having	multiple network interfaces, use this option
	   to select which interface to	use for	connecting to the MySQL

       o   --character-sets-dir=dir_name

	   The directory where character sets are installed. See Section 11.5,
	   "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

       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.

       o   --debug-info

	   Print debugging information and memory and CPU usage	statistics
	   when	the program exits.

       o   --default-character-set=charset_name

	   Use charset_name as the default character set. See Section 11.5,
	   "Character Set Configuration".

       o   --default-auth=plugin

	   A hint about	the client-side	authentication plugin to use. See
	   Section 7.3.8, "Pluggable Authentication".

       o   --defaults-extra-file=file_name

	   Read	this option file after the global option file but (on Unix)
	   before the user option file.	If the file does not exist or is
	   otherwise inaccessible, an error occurs.  file_name is interpreted
	   relative to the current directory if	given as a relative path name
	   rather than a full path name.

       o   --defaults-file=file_name

	   Use only the	given option file. If the file does not	exist or is
	   otherwise inaccessible, an error occurs.  file_name is interpreted
	   relative to the current directory if	given as a relative path name
	   rather than a full path name.

	   Exception: Even with	--defaults-file, client	programs read

       o   --defaults-group-suffix=str

	   Read	not only the usual option groups, but also groups with the
	   usual names and a suffix of str. For	example, mysqlshow normally
	   reads the [client] and [mysqlshow] groups. If the
	   --defaults-group-suffix=_other option is given, mysqlshow also
	   reads the [client_other] and	[mysqlshow_other] groups.

       o   --enable-cleartext-plugin

	   Enable the mysql_clear_password cleartext authentication plugin.
	   (See	Section, "The Cleartext	Client-Side Authentication

	   This	option was added in MySQL 5.7.10.

       o   --host=host_name, -h	host_name

	   Connect to the MySQL	server on the given host.

       o   --keys, -k

	   Show	table indexes.

       o   --login-path=name

	   Read	options	from the named login path in the .mylogin.cnf login
	   path	file. A	"login path" is	an option group	containing options
	   that	specify	which MySQL server to connect to and which account to
	   authenticate	as. To create or modify	a login	path file, use the
	   mysql_config_editor utility.	See mysql_config_editor(1).

       o   --no-defaults

	   Do not read any option files. If program startup fails due to
	   reading unknown options from	an option file,	--no-defaults can be
	   used	to prevent them	from being read.

	   The exception is that the .mylogin.cnf file,	if it exists, is read
	   in all cases. This permits passwords	to be specified	in a safer way
	   than	on the command line even when --no-defaults is used.
	   (.mylogin.cnf is created by the mysql_config_editor utility.	See

       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

	   Specifying a	password on the	command	line should be considered
	   insecure. See Section, "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 using a named pipe. This option
	   applies only	if the server supports named-pipe connections.

       o   --plugin-dir=dir_name

	   The directory in which to look for plugins. Specify this option if
	   the --default-auth option is	used to	specify	an authentication
	   plugin but mysqlshow	does not find it. See Section 7.3.8,
	   "Pluggable Authentication".

       o   --port=port_num, -P port_num

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

       o   --print-defaults

	   Print the program name and all options that it gets from option

       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
	   permissible values, see Section 5.2.2, "Connecting to the MySQL

       o   --secure-auth

	   Do not send passwords to the	server in old (pre-4.1)	format.	This
	   prevents connections	except for servers that	use the	newer password
	   format. This	option was added in MySQL 5.7.4.

	   As of MySQL 5.7.5, this option is deprecated	and will be removed in
	   a future MySQL release. It is always	enabled	and attempting to
	   disable it (--skip-secure-auth, --secure-auth=0) produces an	error.
	   Before MySQL	5.7.5, this option is enabled by default but can be

	       Passwords that use the pre-4.1 hashing method are less secure
	       than passwords that use the native password hashing method and
	       should be avoided. Pre-4.1 passwords are	deprecated and support
	       for them	is removed in MySQL 5.7.5. For account upgrade
	       instructions, see Section, "Migrating Away from Pre-4.1
	       Password	Hashing	and the	mysql_old_password Plugin".

       o   --shared-memory-base-name=name

	   On Windows, the shared-memory name to use, for connections made
	   using shared	memory to a local server. The default value is MYSQL.
	   The shared-memory name is case sensitive.

	   The server must be started with the --shared-memory option to
	   enable shared-memory	connections.

       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 using	SSL and	indicate where to find SSL keys	and
	   certificates. See Section 7.4.5, "Command Options for Secure

       o   --status, -i

	   Display extra information about each	table.

       o   --tls-version=protocol_list

	   The protocols permitted by the client for encrypted connections.
	   The value is	a comma-separated list containing one or more protocol
	   names. The protocols	that can be named for this option depend on
	   the SSL library used	to compile MySQL. For details, see
	   Section 7.4.3, "Secure Connection Protocols and Ciphers".

	   This	option was added in MySQL 5.7.10.

       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

       o   --version, -V

	   Display version information and exit.
