Hello.
I want to write a simple program that will do operations on files that match a given pattern.
My trouble is that I also want to show a dynamically changing preview of a list of files that match that pattern(fixed number of lines), updating it while the user stop typing for a second and I have no idea how to implement that.
It must look like this:
$ Please enter a pattern: '*.pl'
1.pl
2.pl
3.pl
...
Where to start? What is the easiest way to achieve that?

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).

or How to display code and escape characters
are good places to start.
