-.SH NAME
-null, zero \- data sink
-.SH DESCRIPTION
-Data written to the
-.I /dev/null
-and
-.I /dev/zero
-special files is discarded.
-.P
-Reads from
-.I /dev/null
-always return end of file (i.e.,
-.BR read (2)
-returns 0), whereas reads from
-.I /dev/zero
-always return bytes containing zero (\[aq]\e0\[aq] characters).

-mknod \-m 666 /dev/null c 1 3
-mknod \-m 666 /dev/zero c 1 5
-chown root:root /dev/null /dev/zero
-.EE
-.in
-.SH FILES
-.I /dev/null
-.br
-.I /dev/zero
-.SH NOTES
-If these devices are not writable and readable for all users, many
-programs will act strangely.
-.P
-Since Linux 2.6.31,
-.\" commit 2b83868723d090078ac0e2120e06a1cc94dbaef0
-reads from
-.I /dev/zero
-are interruptible by signals.
-(This change was made to help with bad latencies for large reads from
-.IR /dev/zero .)
