Is it possible to do:
echo apassword | su

No. You can set up "sudo" if you need to allow certain commands to run as root from a normal user account.

Alright, i'll look up docs on that, and voidman, you abondoned my post for the laptop. :confused: still dont know what to do about the dvd.

All I want to accomplish is the knowledge of how to send the output of command A to the input of command B. I dont have any specific goal in mind anymore, I just want to learn something new. And this is 1 thing I know how to do in windows but not linux. I'm not so sure how I could get really detailed about it. lets say I make a program that records all the input it gets, and once it stops recieving input for more than 2 seconds it closes. how would I send 'ls' to that program?
