i've ever use grep but it prints only one line
so i dont know how can i get it.

Thanks

ifconfig | grep eth1


This will print all lines containing eth1

Unless you're doing some kind of programming project, I would just use the command:

homey: oh yeah... :D

Sorry, pangcake my mistake. I misunderstood.

will print only the eth1 paragraph

will print everything BUT the eth1 paragraph
