Hey everyone :)
I am very new to Perl and can't understand why I can't check to see if a file is empty in a while loop...
I am building a page for my teacher to be able to change links on a school site anytime he wants through his browers. My script opens a file, reads the lines, splits the contents of the line into an array and displays them (not like you don't understand this already... don't mean to offend any of you :) )
Anyway, if the file is empty, I am trying to redirect to a subroutine called stopit..
open(FILE, "links.dat") || die "Can't open file!";
flock(FILE, 2) || die "Can't lock file!";
while ($line = <FILE>) {
chomp $line;
my @part = split(/\|/,$line);
if ($part[0] eq "") {
&stopit;
}
if ($part[3] eq "new") {
$which = " target=\"_blank\"";
}
print "<li><a href=\"$part[2]\"$which>$part[1]</a></li><br>\n";
}
close(FILE);
print "</ul></body></html>";
sub stopit {
close(FILE);
print "There are currently no links :(";
exit;
}
What am I doing wrong? I thought I could check to see if the first part of the array has a value near the beginning og the while loop?
I know the coding is very crude... please be gentle!!

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).
