If you just want to process the file periodically when it
has changed, you can:
my $old_time = (stat( $file ))[9];
while ( 1 ) {
sleep $period_in_seconds;
my $current_time = (stat($file))[9];
while ( $current_time != $old_time ) {
$old_time = $current_time;
print "file changed$/";
$current_time = (stat($file))[9];
}
}
The above nods at the issue of race conditions; it ignores
possible contention issues.
Be well,

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).
