Something like this?
my @mesages = (...);
my $pass = 0;
for my $message (@messages) {
sleep(5) if !$pass++;
print($message);
}
sleep is interruptible and drift can occur if the loop body is non-trivial, so maybe the following would be better:
use Time::HiRes qw( time sleep ); # Optional
sub sleep_until {
my ($e_time) = @_;
for (;;) {
my $dur = $e_time - time;
last if $dur <= 0;
sleep($dur);
}
}
my @mesages = (...);
my $s_time = time;
for my $i (@messages) {
sleep_until($s_time + 5*$i);
print($message);
}

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).
