    UNIX question

    hi , I just wanna ask if it is possible to do this in UNIX: tar -xvfb 20 /dev/rct0

    and if not , where is the mistake?
    second what's the difference between * and $* in the begging of for when using sh?
    and last what 's doing     echo ${d-$1} combined with a command procedure ?
