There are so many errors in your subroutine that we are not sure what you are trying to do. I recommend that you study the documentation perlsub. I suspect that you are confusing us (and yourself) with a poor choice of variable names ($script1 for the name of a script file and $script2 for its output???). Given the code you have shown, $_ should not contain anything. You probably do not need a subroutine if all it does is extract the directory name from the script output. Use a regex with capture parenthesis in your main program.
We can provide much better help if you post a short program that we can run and duplicate your problem. Use use strict; use warnings and fix all errors and warnings that they cause. (Read the tutorial Short, Self-Contained, Correct Example)

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).
