title: How to replace a comma delimiter in string in csv file Unix - MAC OS
body: <p>I have a CSV file with a comma delimiter and need to remove this delimiter in string to manipulate the data.</p>
  
  <p>The file is like :<br>
  <strong>Col1, Col2, Col3, Col4</strong><br>
  100, 08 sciences, <strong>"xx, yy, ww"</strong>, US<br>
  110, 06 culture, <strong>"abc, ww"</strong>, US<br>
  115, 05 geology, <strong>"geology"</strong>, CA  </p>
  
  <p>I need to scan the string to replace the delimiter but don't know how to proceed.
  I've tried sed 's/"<em>,</em>"/" "/g' (using Mac OS 10.10)</p>
  
  <p>So when I'm trying to keep some column I can't reach the expected result :
  cut -d , -f 2,3 myfile.csv > newfile.csv</p>
  
  <p>I got :<br>
  08 sciences, "xx<br>
  06 culture, "abc<br>
  05 geology, "geology"  </p>
  
  <p>Instead of<br>
  08 sciences, "xx, yy, ww"<br>
  06 culture, "abc, ww"<br>
  05 geology, "geology"  </p>
  
  <p>Any help please ?</p>
