Follows are the solution to this question:
Explanation:
head | tail -n 4380 in the numbers.txt
This will take first 4380 lines head -n 4380
tail -n 4 takes out the last 4 lines
tail -n + 4377.txt | head -n 4 -n
tail -n + 4377 requires all 4377 lines
head -n 4 cuts out first four lines
that's why the final answer is "4380, 4 5624,4".
