Jan 12, 2018 Can't open /dev/null: no such file or folder found. I check directory and file and it exists. How can i work with this problem. TrevorH Forum Moderator Posts: 28115. Mknod /dev/null/ c 1 3 and hit enter. Then i used the passwd command. If you open up another shell, say by using screen or xterm, you can run run echo spooky /dev/pts/2 in that shell to make the text appear on your original terminal, and the same for the other commands. All of this is just your shell opening a file without knowing it's a TTY.
