As documented in system:
Does exactly the same thing as exec, except that a fork is done first and the parent process waits for the child process to exit.
So, if you don't want to wait for the child process to exit (e.g., someone to close the text editor), change that to an exec. It will change the executing process -- mind body and soul -- to be the running text editor, giving up control forever.
You also can remove the exit in that case, too. Please note that exit is almost never what you actually mean to do if you don't need to return a status code. Just let the script roll off the end.

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).
