<b>I have moved a file to /dev/null and now my system doesn't work </b><br><br>
If you move a file with the mv command to "/dev/null" then it will be overwritten with an ordinary file.<br>
<b>How to fix it:</b><br>
Boot your system. If it doesn't boot take a one disk distribution like <a href="http://www.toms.net/rb/home.html">Toms rtbt</a> and mount your /dev/hdXX partition.<br>
Now type in a shell "mknod /dev/null c 1 3" to create a nod file.
/dev/null is the path where the nod file will be saved. The c stands for a character device and the two numbers are the major and the minor numbers for the null device.<br>
After that you must change with "chmod 666 /dev/null" the read, write and execute permissions.<br><br>
With "ls -alF /dev/" you will see all nod files with it's own three parameters like<br>
"crw-rw-rw-   1 root     root       1,   3 Oct  4 11:34 null ".<br>
You will see a "c" in the near of the rwx flags an a " 1, 3" left of the date.
