There is a difference between Perl closing a filehandle (meaning you cannot access it in your code) and Perl flushing an output buffer (meaning all the contents have been written to disk). The buffer will definitely be flushed at the end of the script. However, if you need immediate flushing, add $| =1; right after your open() call. Alternately, take a look at IO::File and the flush() method. (Due to the documentation style of the IO distribution, you actually have to look at IO::Handle for the documentation of the flush() method. But, it is available from IO::File objects.)
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
-

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).
