title: Moving All Files From Directories One Step Up
body: <p>I have a directories that look like this</p>
  
  <pre><code>fool@brat:/mydir/ucsc_mm8&gt; tar -xvf *.tar 
  1/chr1.fa.masked
  1/chr1_random.fa.masked
  2/chr2.fa.masked
  3/chr3.fa.masked
  4/chr4.fa.masked
  5/chr5.fa.masked
  5/chr5_random.fa.masked
  19/chr19.fa.masked
  Un/chrUn_random.fa.masked
  </code></pre>
  
  <p>What I want to do is to move out all the "*.masked" files in the subdirectories <code>/1</code> upto <code>/Un</code>.
  Is there a compact way to do it in Linux/Unix?</p>
