title: Securely remove file from ext3 linux
body: <p>This question has been asked with varying degrees of success in the past...</p>
  
  <p>Are there tools, or C/C++ unix functions to call that would enable me to retrieve the location on disk of a file? Not some virtual address of the file, but the disk/sector/block the file resides in?</p>
  
  <p>The goal here is to enable overwriting of the actual bits that exist on disk. I would probably need a way to bypass the kernel's superimposition of addresses. I am willing to consider an x86 asm based solution... </p>
  
  <p>However, I feel there are tools that do this quite well already. </p>
  
  <p>Thanks for any input on this.</p>
