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:root /dev/null /dev/zero

 

FILES


       /dev/null
       /dev/zero

 

NOTES


       If these devices are not writable and readable for all users, many pro-
       grams will act strangely.
