I asked you to use code tags and explained how to do. Next time use them please. If you don't understand what I am talking about, please say so.

That excerpt is very short but I think I got it. Maybe it's easier to use something like "ranges" in sed or awk if you take over the part of looking up where the 30 days ago start, so you can skip calculating the last 30 days. Example:

Input
Code:
prueba|14/03/2009|00:00:02|NODO_STATUS|UP|
prueba|21/03/2009|00:00:02|NODO_STATUS|UP|
prueba|05/04/2009|00:00:02|NODO_STATUS|UP|
prueba|23/04/2009|00:00:02|NODO_STATUS|UP|
prueba|02/05/2009|00:00:02|NODO_STATUS|UP|
prueba|11/05/2009|00:00:02|NODO_STATUS|UP|
prueba|11/05/2009|00:00:02|NODO_STATUS|UP|
prueba|20/05/2009|00:00:02|NODO_STATUS|UP|

Cmd and output
Code:
$> sed '/23\/04\/2009/,/20\/05\/2009/!d' infile
prueba|23/04/2009|00:00:02|NODO_STATUS|UP|
prueba|02/05/2009|00:00:02|NODO_STATUS|UP|
prueba|11/05/2009|00:00:02|NODO_STATUS|UP|
prueba|11/05/2009|00:00:02|NODO_STATUS|UP|
prueba|20/05/2009|00:00:02|NODO_STATUS|UP|
