title: How to recover a file overwritten with another in Linux?
body: <p>I did this on the command line(Ubuntu 12.04)</p>
  
  <p>mv some_arbit_file required_file</p>
  
  <p>Is there any way I can recover required_file. I had put so much work into this. I usually backup files. But, I forgot this time. Will appreciate any help.</p>
  
  <p>Thanks.</p>
