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.

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).
