Question

I have a simple question. Is there a command that allows you to pull a certain line out of an input? Like if I wanted the 7th line from ifconfig. Is there a way to do this: ifconfig | [command] 7?

Thanks!

YOu can use sed to extract a particular line from a file and/or from standard in as follows

sed -n '7p' filename or

some_command | sed -n '7p'
