       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. 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] option file groups.  mysqlshow also supports the options for
       processing option files described.

       ·   --help, -?

           Display a help message and exit.

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

           The directory where character sets are installed.

       ·   --compress, -C

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

       ·   --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

       ·   --default-auth=name

           Default authentication client-side plugin to use.

       ·   --default-character-set=charset_name

           Use charset_name as the default character set.

       ·   --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.

       ·   --defaults-file=filename

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

       ·   --defaults-group-suffix=suffix

           In addition to the groups named on the command line, read groups that have the given

       ·   --host=host_name, -h host_name

           Connect to the MariaDB server on the given host.

       ·   --keys, -k

           Show table indexes.

       ·   --no-defaults

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

       ·   --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. You can use
           an option file to avoid giving the password on the command line.

       ·   --pipe, -W

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

       ·   --plugin-dir=dir_name

           Directory for client-side plugins.

       ·   --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 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.

       ·   --print-defaults

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

       ·   --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

           Enable SSL for connection (automatically enabled with other flags). Disable with

       ·   --ssl-ca=name

           CA file in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-capath=name

           CA directory (check OpenSSL docs, implies --ssl).

       ·   --ssl-cert=name

           X509 cert in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-cipher=name

           SSL cipher to use (check OpenSSL docs, implies --ssl).

       ·   --ssl-key=name

           X509 key in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-crl=name

           Certificate revocation list (check OpenSSL docs, implies --ssl).

       ·   --ssl-crlpath=name

           Certificate revocation list path (check OpenSSL docs, implies --ssl).

       ·   --ssl-verify-server-cert

           Verify server's "Common Name" in its cert against hostname used when connecting. This
           option is disabled by default.

       ·   --status, -i

           Display extra information about each table.

       ·   --user=user_name, -u user_name

           The MariaDB 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.
