There are 2 bugfixes. - Since `wc -l FILE` returns not only line number but also FILE filename, following "if" statement always failed. Fix this bug by replacing it with 'cat FILE | wc -l' - Since "while do-done loop" block with pipeline becomes a subshell, $N local variable is not update outside of the loop. Fix this bug by using actual target number (256) instead of $N.
