Thank you for adding a test. We have a helper function test_line_count which provides a helpful debugging message if the comparison fails. Using that and avoiding process substitutions we'd write
sort head >sorted_head && sort cmp >sorted_cmp && comm -12 sorted_head sorted_cmp >actual && test_line_count = 0 actual Thanks Phillip
