Well it seems there are bugs with the UnxUtils version of tail as well. When using it in a perl script with any form of the "follow" options (e.g., "tail -f", "tail --follow", etc.) it never gives anything and the tail.exe process needs to be maually killed. "tail -f" works OK on the commandline except when its output is piped to another process (even "cat".) When run without the '-f' however, it works as one would expect.
Still looking for a better solution and will update this thread once I find one.
$fh->open("tail.exe --follow=name tls.log|") || die $!;
print("opened: '$fh'\n");
while(my $c = $fh->getc) { # hangs here. tried getline also
print("$c");
}
print("closing: '$fh'\n");
close($fh);

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).
