NAME

     null, zero - data sink

DESCRIPTION

     Data written on a null or zero special file is discarded.

     Reads from the null special file always return end of  file,
     whereas reads from zero always return \0 characters.

     null and zero are typically created by:

          mknod -m 666 /dev/null c 1 3
          mknod -m 666 /dev/zero c 1 5
          chown root.mem /dev/null /dev/zero

NOTES

     If these devices are  not  writable  and  readable  for  all
     users, many programs will act strange.

FILES

     /dev/null
     /dev/zero
