print substr($String, 0, 10);
<Update> SteveAZ98 is right: substr will not pad the string to a fixed length, if it is not longer than the desired width...</Update>

Engaging in one of my favorite PM activities, I benchmarked pack vs. substr:

timethese(1000000, { pack => q{ my $String = 'Russ is a stud'; $String = pack("A10", $S +tring)}, substr => q{ my $String = 'Russ is a stud'; $String = substr($String +, 0, 10)} });
With these results:
Benchmark: timing 1000000 iterations of pack, substr... pack: 7 wallclock secs ( 7.20 usr + 0.00 sys = 7.20 CPU) substr: 6 wallclock secs ( 6.67 usr + 0.01 sys = 6.68 CPU)
I just love wasting time with benchmarks, perl golf, etc.

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.
