How does one display certain lines of a file in Linux (several lines in the middle)

[1] 3,000th rows are displayed starting from 1000 rows. Display 3000 ~ 3999 rows

Cat filename | tail-N + 3000 | head-N 1000

 

[2] display rows 1000 to 3000

Cat filename | head-N 3000 | tail-N plus 1000

 

* Pay attention to the order of the two methods

 

Decomposition:

Tail-N 1000: displays the last 1000 rows

Tail-N + 1000: The value ranges from 1000 rows to 1000 rows.

Head-N 1000: displays the first 1000 rows

 

[3] use the SED command

 

Sed-n'5, 10p' filename so that you can view only rows 5th to 10th of the file.
