Sure you can, but that's not what your code does. If you want to sort column 16, you will first have to select the 16th column entirely, before you can sort it. So you would do:
  1. Open your input file.
  2. Read it, line by line. Extract column 16, push it to an array.
  3. Close your input file.
  4. Sort your array.
  5. Open your output file.
  6. Write your sorted array.
  7. Close your output file.
What you certainly can't do is reading the input one line at a time, writing something for each line, and then expect the entire thing to be sorted when you're done.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
