/usr/bin/mariadb-show  Ver 9.10 Distrib 10.6.28-MariaDB, for Linux (x86_64)
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Shows the structure of a MariaDB database (databases, tables, and columns).

Usage: /usr/bin/mariadb-show [OPTIONS] [database [table [column]]]

If last argument contains a shell or SQL wildcard (*,?,% or _) then only
what's matched by the wildcard is shown.
If no database is given then all matching databases are shown.
If no table is given, then all matching tables in database are shown.
If no column is given, then all matching columns and column types in table
are shown.

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
The following groups are read: mysqlshow mariadb-show client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults          Print the program argument list and exit.
--no-defaults             Don't read default options from any option file.
The following specify which files/extra groups are read (specified before remaining options):
--defaults-file=#         Only read default options from the given file #.
--defaults-extra-file=#   Read this file after the global files are read.
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.

  -t, --show-table-type
                      Show table type column.
  -S, --socket=name   The socket file to use for connection.
  --ssl               Enable SSL for connection (automatically enabled with
                      other flags).
  --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 (implies --ssl).
  --ssl-cipher=name   SSL cipher to use (implies --ssl).
