zero

NULL(4)			  Linux Programmer’s Manual		      NULL(4)



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
