Command to get nth line of STDOUT

Question

Is there any bash command that will let you get the nth line of STDOUT?

That is to say, something that would take this

$ ls -l
-rw-r--r--@ 1 root  wh         


        

Answer 1

For more completeness..

ls -l | (for ((x=0;x<2;x++)) ; do read ; done ; head -n1)

Throw away lines until you get to the second, then print out the first line after that. So, it prints the 3rd line.

If it's just the second line..

ls -l | (read; head -n1)

Put as many 'read's as necessary.
