When I try to delete a file

sudo rm -rf filename

I get spit back:

rm: filename: Resource is busy

How can I override this? I know for a fact that the resource is not busy. I just want to delete it!

The operating system says it is. Should we trust the computer or the human? Do you have the file selected in any GUI? Is it actually a directory (noting that you used the -r flag)? Is it perhaps open in a background or zombied process? –  paddy Feb 12 '13 at 22:26

And so you are therefore certain that the file is not being used by a process that is started when your system starts? The key to being a good problem solver is to not trust anything you're told. I don't trust you, and I don't trust your operating system. With a level playing field, we can make some progress into understanding what is going on. If we accept all your assumptions as true, we will make no further progress than you have already, and look where you are right now. –  paddy Feb 12 '13 at 22:33

It's BUSY! The OS is not going to have a bar of it. Furthermore, you are ignoring what is being said and returning to "answer the question". Have you tried booting your system from an image on a flash drive or whatever, mounting the partition in question and deleting the file? –  paddy Feb 12 '13 at 22:42

No, I'm trying to get to the bottom of what is causing the problem because you want to delete the file. Instead of being unhelpful by saying "you can't", I'm trying to say "let's find a way to delete the file". I still think the file is in use, but you refuse to entertain that argument and so this discussion gets silly. Try booting from an image, mounting the partition and removing the file. If that doesn't work, then something is up with your file system, or the file isn't really a file. –  paddy Feb 12 '13 at 22:54

Then I misunderstood the last part of your question where you say "I just want to delete it!" You don't seem open to advice on how to achieve this, so I recommend you continue to follow your own path without asking for help. –  paddy Feb 12 '13 at 23:01

As other posters say, if you know better then the OS, reboot the system and that will make it forget. But really, they know what they are talking about...

You have demanded an answer to your question, ignoring all discussion along the way, and providing attitude to boot. I find your comments both ignorant and insulting, given that I am taking time to work through a problem that has absolutely no significance to me. You have also ignored the existing answer by Paul Tomblin where he asks if you have tried lsof.

So here is my answer: You cannot override this behaviour.

The operating system states that it is busy. The operating system is probably correct. The error message could be for these reasons:

  • the file is actually being used by another process
  • there is a problem with your file system

As you wish to delete the file, my suggestion has been to boot the machine from a linux image, mount your file system and delete the file. You have not accepted this as a course of action to try.

In future, please consider the manner in which you ask for and receive help from others. If you are unwilling to take advice or answer questions, do not ask for help.

One could add, that Apple's "Preview" is a common reason for random files to be "busy" if you previewed them with the space-bar "QuickLook" feature. I absolutely hate it and it is driving me nuts. I would also suggest adding the lsof file and how to proceed - kill the PID and then delete the file. One could also write a hard-core-delete script, that does this. But yes, that is far beyond answering a simple question like this ;) –  YoshiBotX May 12 at 16:10

Try lsof filename to see if it's really busy. One of the most common causes of this is that you're trying to remove a directory that you have a shell open in.

It is not busy....trust me. Please just answer the question :) –  CodeGuy Feb 12 '13 at 22:30

Did you try the command? Unix usually doesn't lie about things just to mess with you. –  Paul Tomblin Feb 12 '13 at 22:31
