  mknod

 SYNTAX

       /etc/mknod  name  c  |  b  major minor

 FUNCTION

       mknod makes a directory entry and a

       corresponding i-node for a special file.

 OPTIONS

       -c    -    If the special file is character/serial type.

       -b    -    If the special file is block/parallel type.

 NOTE:   name - is the special file name; major and minor 

                are device numbers and are specific to each 

                system.  They have to come from the system 

                source file conf.c.

 Let us use the mknod command to make a special file 

 /dev/tty07 which is character-special and has a major 

 device number of 0 and a minor device number of 7.

 So please enter:  mknod /dev/tty07 c 0 7

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please type mknod /dev/tty07 c 0 7 

 Please type mknod /dev/tty07 c 0 7 

 I guess I must type this for you:

FORGET1

 mknod /dev/tty07 c 0 7               

 Observe the result on the terminal!

 $PROMPT$

 Let us verify that indeed such a file was

 created by typing:  ls -l /dev/tty07

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please type ls -l /dev/tty07

 Please type ls -l /dev/tty07

 I guess I must type this for you:

 $PROMPT$

FORGET2

 ls -l /dev/tty07               

 Observe the result on the terminal!

 crw-r--r--  1  root  0,  7 /dev/tty07
