Linux Cat displays several lines

"One" starts at line No. 3000 and displays 1000 rows. The 3000~3999 line is displayed

Cat FileName | Tail-n +3000 | Head-n 1000

"Two" displays 1000 rows to 3000 rows

Cat filename| Head-n 3000 | Tail-n +1000

* Note the order of the two methods

Decomposition:

Tail-n 1000: Show last 1000 rows

Tail-n + 1000: Starting from 1000 lines, showing 1000 rows later

Head-n 1000: Show front 1000 lines

"Three" with sed command

Sed-n ' 5,10p ' filename so you can only view lines 5th through 10th of the file.
