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.
