title: german to english float system in bash
body: <p>When I try to run a for loop in my bash script with an incrementation of 0.5. The script gives the output in the German floating system. 
  eg:</p>
  
  <pre><code>for i in $(seq 2.0 0.5 4.0)
  do
  echo $i
  done
  </code></pre>
  
  <p>The output it gives is :</p>
  
  <pre><code>2,0
  2,5
  3,0
  3,5
  4,0
  </code></pre>
  
  <p>I need to fix this because most of my files are named according to these numbers. With this error, my script is unable to read such files. Any suggestions ?</p>
