I'm now using the below. Anyone see any problems? Should I still use truncate($fh, 0); after seek or does the sysopen take care of that? sub safe_open {
my $fn = shift;
$fn =~ s/^(>>?)//;
$mode = length($1);
my $flags = $mode == 1 ? O_CREAT | O_WRONLY | O_TRUNC :
$mode == 2 ? O_CREAT | O_WRONLY | O_APPEND :
O_RDONLY;
sysopen(my $fh, $fn, $flags) or die "Can't open $fn: $!";
if ($flock_enabled) {
flock($fh, LOCK_EX) or die "Can't flock $fn: $!";
}
seek $fh, 0, 0;
return $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).

are good places to start.
