Within "myscript.prl" instead of just printing and capturing STDOUT to $tmp_file, open it instead and write to it. You will want to checkout flock which may help prevent the overwriting problem. Still, if you have hundreds of thousands of processes/machines all trying to write to the same file, you are creating a huge bottleneck. What about running the command on each machine as you appear to want to do, but write it to a local temporary accumulation file. Then either retrieve each one, or send them to a common queue (on a periodic basis) where a second process can collate them into this one behemoth file you desire? Just a thought.

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).
