(BASH) Let us say a test is conducted to assess the typing speed for applicants. We need to count # of correctly spelled words and penalize for incorrectly spelled words. score = (# of correctly spelled words) - 2 * (# of incorrectly spelled words) Assuming filename is words.txt, write a one-line command to compute the score.
