I don't think that this is the best way...
BrowserUk and I both used the core module: List::Util::shuffle;

He understood the FASTA format better than I did and that is fine given that the format of the OP's question was hard to "decode".

The main point is that is that this core shuffle() function works very well, is very fast (a core function that is implemented in 'C') and who's interface is easy to understand. I recommend using it rather than trying to "roll your own".

Oh, BTW, "Core Function" means that this is available on all Perl systems as part of the language - no "extra module installation" is required. .... Well I don't know exactly about "all", but I figure since Perl 5.6 (for more than decade).

Title:
Use:  <p> text here (a paragraph) </p>

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.
