/dev/null is nothing, empty void. If you move something there it just gets deleted
You can’t move anything there, it’s a “character special file” that can’t be deleted. If you pipe something there, it does nothing. (As opposed to something like /dev/stdin, that prints what you pipe to it on stdin.) Character special files act kind of like named pipes, except they’re handled by the kernel on one side. They’re raw device files.
It's a "null drive". Anything that goes in is just simply discarded and a EOF is sent in return. If you "move" a file there, it just gets discarded
Just try it. I’m literally telling you the truth. It is not a drive, and you cannot move files to it. It doesn’t have a file system, and you can’t create one on it. It cannot be mounted like a drive. Drives are block special files, and /dev/null is a character special file, not a block special file.
I see, you're right, you can't
mvinto it, but you can shove streams of data to it
