title: Sort command included in Cygwin launched by normal Windows promppt don't accept $ operator for tab character
body: <p>I have installed Cygwin on my machine and I would to know if there exist a way to use full power of sort command also with the normal DOS prompt.</p>
  
  <p>I have read this question: <a href="https://stackoverflow.com/questions/1037365/unix-sort-with-tab-delimiter">Unix Sort with Tab Delimiter</a>
  and the command to sort a tabbed file using the second column is:</p>
  
  <pre><code>sort -t $'\t' -k 2 file.txt
  </code></pre>
  
  <p>If I launch the command inside the Cygwin environment it works like expected, if I launch it from the normal Windows prompt (I have renamed sort.exe into xsort.exe to avoid conflicting with native Windows sort command) it doesn't works, it not recognize the $ operator and it see \t like two distinct characters and operation fails.</p>
  
  <p>Is it possible to make it working also from the DOS prompt?</p>
