title: Deleting Files Permanently and Securely on CentOS
body: <p>I would like to know how would to permanently and securely delete files on CentOS. The problem I'm having right now is that, the filesystem is ext3, and when I thought of using <code>srm-</code> it said something like </p>
  
  <blockquote>
    <p>"It should work on ext2, FAT-based file systems, and the BSDnative file system. Ext3 users should be especially careful as it can be set to journal data as well, which is an obvious route to reconstructing information."</p>
  </blockquote>
  
  <p>If I can't use <code>shred</code> or <code>srm</code>, and secure-delete is also not an option, I'm clueless about how to securely and permanently delete the data. The files I'm deleting are NOT encrypted. </p>
