You could also use a here-document if your shell supports it (most do):

psql rnd <<END_OF_SQL
select * from table1;
select * from table2;
select * from table3;
END_OF_SQL

You could use the PGPASSWORD environment variable, although doing
so is deprecated due to the security risk (many operating systems
make environment variables visible to other processes).  Another
possibility would be to use ~/.pgpass; see "The Password File"
in the libpq chapter of the documentation.  Or, if the security
model allows it, tweak pg_hba.conf so it doesn't require password
authentication (some security can be maintaned by using ident
authentication if the system supports it).
