grep tail and head wrong result

Question

I want to show the 3 first lines and the 2 last lines that contain a word. I tried a grep command but it's not showing what I want.

grep -w it /usr/include/stdio.h | head -3 | tail -2

It only display the 2nd and 3nd lines that contain "it" in it.

Answer 1

You can simply append the results of head and tail :

{ head -3 ; tail -2 ;} < /usr/include/stdio.h
