> Eg. In abcdabcdabceabcdabcdabceab; abcd is a false rep; the required rep is abcdabcdabce;
since regex are greedy, this works for me
DB<131> $_='abcdabcdabceabcdabcdabceab'
=> "abcdabcdabceabcdabcdabceab"
DB<132> ($match)= /(.+)\1/
=> "abcdabcdabce"
edit: I doubt that the answer is so simple, but this should give you a start to ask more precisely...

Are you posting in the right place? Check out Where do I post X? to know for sure.

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.
