G'day live4tech,

I see you've resolved your problem. There can be rare instances when you want to preserve all the input, including terminal newlines. In these cases, you can use \Z (uppercase) instead of the more usual \z (lowercase).

$ perl -Mstrict -Mwarnings -E ' while (<>) { say "z-match" if /\A\d+[a-z]+\z/; say "Z-match" if /\A\d+[a-z]+\Z/; } ' 123dog Z-match

Details are in: perlre - Regular Expressions under Assertions.

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.
