1. sed command
2. cat command
3. less command
4. awk command
5. mapfile command (Bash v4.x only)

To display 1 to 10 lines from /etc/passwd file and number all output lines, enter:

sed -n "1,10p" /etc/passwd | cat -n

Sample outputs:

sed -n "50,200p" /etc/passwd | less -N

The following example use the head command to display first 10 lines of /etc/passwd file:

head +10 /etc/passwd | cat -n

Sample outputs:

     1	==> /etc//passwd <==
     2	root:x:0:0:root:/root:/bin/bash
     3	bin:x:1:1:bin:/bin:/sbin/nologin
     4	daemon:x:2:2:daemon:/sbin:/sbin/nologin
     5	adm:x:3:4:adm:/var/adm:/sbin/nologin
     6	lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin
     7	sync:x:5:0:sync:/sbin:/bin/sync
     8	shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown
     9	halt:x:7:0:halt:/sbin:/sbin/halt
    10	mail:x:8:12:mail:/var/spool/mail:/sbin/nologin
    11	uucp:x:10:14:uucp:/var/spool/uucp:/sbin/nologin

Display 10-20 lines using head and tail combo as follows:

head -20 /etc/group | tail -n 10 | cat -n

Sample outputs:

     1	nobody:*:-2:
     2	nogroup:*:-1:
     3	wheel:*:0:root
     4	daemon:*:1:root
     5	kmem:*:2:root
     6	sys:*:3:root
     7	tty:*:4:root
     8	operator:*:5:root
     9	mail:*:6:_teamsserver
