I found that it cannot boot into the system.. How can i get /dev/null back??can i creat this files (device)??or can i get it from someone then put it back??Thank you.

dev/null, isn't that the trash can? just boot from your cd and type rescue. you might be able to fix it from there.as far as i remember, when you send something to /dev/null, it's just plain gone

Might need to boot into rescue mode, but next time be a little more careful :Pmknod -m 666 /dev/null 1 3Cheers,MC

Yup MC's solution will definitely work.. or else in some special cases you can try this too:

/bin/mknod -m 666 /dev/null c 2 2

 

The option c will create a character (unbuffered) special file.

 

The *NIX command mknod is used to make block or character special files. The permission set 666 is needed because the /dev/null is set as:

CONSOLE

shell> ls -l /dev/null

crw-rw-rw- 1 root root 1, 3 Feb 24 2004 /dev/null

A script named MAKEDEV is available in most of linux distribution. If you are puzzled about the major and minor number of device or only tired to do this, MAKEDEV is a good solution.

Arent such things only possible if you are under root?Try to use normal user accounts as often as possible, and for special actions switch to root.
