Method 1
mknod /dev/null c 1 3 chmod 666 /dev/null
Use these command to create /dev/null or use null(4) manpage for further help.
Method 2
Under many traditional unices, you can recreate devices with their default permissions with the MAKEDEV script. This script is traditionally in /dev but is in /sbin on Ubuntu. Pass it an argument that indicates what devices you want to create; on Ubuntu that’s std (you can write MAKEDEV null as well, that creates null as well as a number of other devices).
Under modern Linux systems running udev, you can tell udev to recreate all or some devices based on available drivers and connected hardware, through udevadm trigger:
udevadm trigger --sysname-match=null
Method 3
When I accidentally deleted /dev/null, a simple sudo rebootseemed to restore it.
It did cause my desktop icons to go crazy, but no damage seemed to be done
If that doesn’t the other answers probably will be more help
