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

Usage: /usr/bin/mysqlshow [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/mysql/my.cnf /etc/my.cnf ~/.my.cnf
The following groups are read: mysqlshow client
