  NAME

    null, zero - data sink

  DESCRIPTION

    Data written to /dev/null or /dev/zero is discarded. When data is read
    from null, it always returns end-of-file; when data is read from zero, it
    always returns \0 (null) characters.

    These files can be created using the following commands:

    /usr/sbin/mknod -m 666 /dev/null c 48 0
    chown $(hostname)+Administrator:+Administrators null
    /usr/sbin/mknod -m 666 /dev/zero c 48 3
    chown $(hostname)+Administrator:+Administrators zero

  NOTE

    If these files cannot be read and written to by all users, some programs
    will not operate properly.
