MYSQLSHOW(1)                 MySQL Database System                MYSQLSHOW(1)



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 13.7.5, "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]]]

       ?   If no database is given, a list of database names is 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.

       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 4.2.6, "Using Option Files".

       ?   --help, -?

           Display a help message and exit.

       ?   --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 server.

           This option is supported beginning with MySQL 5.6.1.

       ?   --character-sets-dir=dir_name

           The directory where character sets are installed. See Section 10.5, "Character Set Configuration".

       ?   --compress, -C

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

       ?   --count

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

       ?   --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.

       ?   --debug-check

           Print some debugging information when the program exits.

       ?   --debug-info

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

       ?   --default-character-set=charset_name

           Use charset_name as the default character set. See Section 10.5, "Character Set Configuration".

       ?   --default-auth=plugin

           A hint about the client-side authentication plugin to use. See Section 6.3.7, "Pluggable Authentication".

           This option was added in MySQL 5.6.2.

       ?   --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.

       ?   --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.

       ?   --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.

       ?   --enable-cleartext-plugin

           Enable the mysql_clear_password cleartext authentication plugin. (See Section 6.5.1.7, "The Cleartext
           Client-Side Authentication Plugin".)

           This option was added in MySQL 5.6.28.

       ?   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       ?   --keys, -k

           Show table indexes.

       ?   --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).
           This option was added in MySQL 5.6.6.

       ?   --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 mysql_config_editor(1).)

       ?   --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 6.1.2.1, "End-User
           Guidelines for Password Security". You can use an option file to avoid giving the password on the command
           line.

       ?   --pipe, -W

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

       ?   --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 6.3.7, "Pluggable
           Authentication".

           This option was added in MySQL 5.6.2.

       ?   --port=port_num, -P port_num

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

       ?   --print-defaults

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

       ?   --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 4.2.2, "Connecting to the MySQL Server".

       ?   --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 is enabled by default; use --skip-secure-auth to disable
           it. This option was added in MySQL 5.6.17.

               Note
               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
               will be removed in a future MySQL release. For account upgrade instructions, see Section 6.5.1.3,
               "Migrating Away from Pre-4.1 Password Hashing and the mysql_old_password Plugin".

       ?   --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.

       ?   --show-table-type, -t

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

       ?   --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.

       ?   --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 6.4.5, "Command Options for Secure Connections".

       ?   --status, -i

           Display extra information about each table.

       ?   --user=user_name, -u user_name

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

       ?   --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.

       ?   --version, -V

           Display version information and exit.
