    Which of the following is true about the null device /dev/null? Choose all that apply:

    1. It is a virtual file
    2. Data written to this file is discarded
    3. This file produces output but discards input
    4. Similar to the Windows (DOS) file NUL
    5. Similar to the Amiga devices file NIL
    6. Receives data through redirection

    Answer later.

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

    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. :tongue

    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. :x

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