mnesia:create_table(TableName, [{disc_copies, [node()]},
				{attributes, [...]}]).

will create a table which resides on disk and in RAM on the current
node.


mnesia:create_table(TableName, [{disc_only_copies, [node()]},
				{attributes, [...]}]).

will create a table which resides on disk only.


Typically, attributes are given with the following construct:

{attributes, record_info(fields, RecName)}


If you want the entire sequence of commands:

erl -sname foo
foo@REDACTED 1> mnesia:create_schema([node()]).
foo@REDACTED 2> mnesia:start().
foo@REDACTED 3> mnesia:create_table(...).

This will:
1. start an Erlang node with the "shortname" foo@<hostname>
2. create a mnesia schema under <CWD>/Mnesia.foo@<hostname>/
3. start mnesia
4. create a table as above
