title: Extract selected data from a .csv file to another
body: <p>I need to know if it's possible to create a batch .bat file to extract from a .csv several rows and save these selected rows into another .csv file. I have read another topics on this webpage and i can only find how to split my csv in several files cutting it by a defined number of rows (for example cutting it in csv files of 500 rows max.).</p>
  
  <p>In the csv files which i would like to manage there are several rows of data with the same structure. </p>
  
  <p>I want to extract into another .csv file some rows of these filtering by a ticket number which is located in each row at a certain position. I don't want to make any change at the original file where the files will be exported, I only want to copy these files into another .csv. For example if i have these rows:</p>
  
  <pre><code>19/09/2013 123456789
  19/09/2013 231564215
  19/09/2013 456464231
  19/09/2013 564659832
  19/09/2013 000000054
  </code></pre>
  
  <p>As is shown, the ticket numbers is located always between the 12th and the 21st position. In this example i want to extract to another csv file the rows with the ticket numbers "231564215" and "564659832". So the data inside the new .csv file must be:</p>
  
  <pre><code>19/09/2013 231564215
  19/09/2013 564659832
  </code></pre>
  
  <p>I need the script to ask you for the name of the original file from where you want to extract and save the data, and obviously to ask you for the number of the tickets you would like to extract (separated by carriage returns for example). The sequence i will like to get is something like this:</p>
  
  <pre><code>CMD Says: Please select the file you would like to convert
  I type: c:/Documents and setting/Marta/testFile.csv
  CMD Says: Please enter the list of tickets you want to export
  I type: 231564215
  564659832
  CMD Says: Exporting data...
  CMD: Export process finished. Your new file is c:/Documents and setting/Marta/exportedData.csv
  </code></pre>
