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.
