In this comparison, we want to know whether the number of lines is greater than 1. Our test_line_count function passes the first argument as the comparison operator to test, so what we want is a numerical comparison, not a string comparison. While this does not produce a functional problem now, it could very well if we expected two or more items, in which case the value "10" would not match when it should. Furthermore, the "<" and ">" comparisons are new in POSIX 1003.1-2024 and we don't want to require such a new version of POSIX since many popular and supported operating systems were released before that version of POSIX was released. Finally, zsh's builtin test operator does not like the greater-than sign in "test", since it is only supported in the double-bracket extension. This has been reported and will be addressed in a future version, but since our code is also technically incorrect, as well as not very compatible, let's fix it by using a numeric comparison.
