For simple queries you can use psql -c:

psql -c 'SELECT * FROM foo'

You can embed an SQL script with a "here document" if your shell
supports it (it probably does):

#!/bin/sh

echo "before database connection"

psql <<END_OF_SQL
CREATE TABLE foo (x integer);
INSERT INTO foo VALUES (42);
SELECT * FROM foo;
DROP TABLE foo;
END_OF_SQL

echo "after database connection"

See your shell's documentation for details. See also the psql
documentation for its options and ways to control its output.
