print OUT if ((s/m/$uut_names[$i]/) && (s/in1/$nets[$i]/) && (s/output/$enabled_nets[$i]/)); there is no output being written to file here
You are missing the while (<IN>) { ... } loop around this statement. print defaults to writing $_ when called without arguments or only a file handle.
Stupid demo:
>perl -E "open IN,'<','/etc/group'; open OUT,'>','/tmp/foo'; while (<I
+N>) { print OUT if /adm/; } close OUT; close IN;"
>cat /tmp/foo
sys:x:3:root,bin,adm
adm:x:4:root,adm,daemon
disk:x:6:root,adm

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
