Start SQL*Plus:
sqlplus /nolog

And use the following commands to shut an instance down:
SQL> connect system as sysdba;
SQL> shutdown immediate;

Use 'shutdown abort;' in case there are hanging connections/processes, but keep in mind that this kills those processes (i.e. use at your own risk).

Shutdown + Start:
sqlplus /nolog

SQL> connect system as sysdba;
SQL> startup force;
