title: Removing 10 Characters of Filename in Linux
body: <p>I just downloaded about 600 files from my server and need to remove the last 11 characters from the filename (not including the extension). I use Ubuntu and I am searching for a command to achieve this.</p>
  
  <p>Some examples are as follows:</p>
  
  <p><code>aarondyne_kh2_13thstruggle_or_1250556383.mus</code> should be renamed to <code>aarondyne_kh2_13thstruggle_or.mus</code></p>
  
  <p><code>aarondyne_kh2_darknessofunknow_1250556659.mp3</code> should be renamed to <code>aarondyne_kh2_darknessofunknow.mp3</code></p>
  
  <p>It seems that some duplicates might exist after I do this, but if the command fails to complete and tells me what the duplicates would be, I can always remove those manually.</p>
