I"m going with number 2. I feel a furball coming on.

 

You might want to read the question again, especially the part that says Choose all that apply.

 

Your lucky you got that much out of me.

 

Well then, since you're feeling adventurous, why not take a crack at the other Linux+ questions. Who knows? Once Ryan pops in and starts posting, it'll be all over anyway.

 

1, 2, and 6 for me.

 

1, 2 and 5 possibly
not sure on this one

 

1, 2 and 4. I think that 6 is possible, but doesn't have to

 

The only thing I can find on that stupid null device is
"On Unix and Linux platforms, the null device (/dev/null) accepts and reads data as does any ordinary file, except with the behaviour of immediately discarding it."

grrr, I knew there was a reason I didn't like linux.

 

Answer time: All answers are correct except for 3. /dev/null does *not* product output of any sort.
