NULL
NAME DESCRIPTION NOTES FILES SEE ALSO
null, zero - data sink
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
If these devices are not writable and readable for all users, many programs will act strange.
/dev/null /dev/zero
