So here is the command Trevor is trying to show you    dmesg | more      Now personally, I would pipe it to less as I think less is 

more than more.  Wait, did that make sense?

    dmesg is command that gives you what has happened with the 

kernel.      The pipe symbol "|" means send the screen output of the dmesg

command to <next command>. In this case, <next command> 

is "more".  More is a process that takes input and 

displays it one screen at a time instead of just running 

off the top of your monitor into some fabled bit bucket.      I am certain Trevor would have made it this detailed but was 

in a hurry.  No offense Trevor.  I personally think this is

still way beyond the Newbie level but if you want to go on

with the research, you will learn a great deal.  You 

will just have to keep coming to this list or to google to 

learn what things you see and should do are.
