Demystifying Regular Expressions
In this article a simple usage of regular expressions is described. Its intention is to bring users to try the most powerful search and replace paradigm available and hopefully start using it.

The article is written reproducing actual steps I took to complete my task, to show the specifics and possible problems.
There is nothing harder then starting to learn something from the beginning. This is even harder if the thing that needs mastering is also something that requires logic and deeper understanding and not just following the protocols. The difference between understanding and knowing is enormous. Real understanding will never let you down, but it might require longer period of time to acquire. It will last longer and it's easier to upgrade if the situation you find yourself in, requires so. Some time ago I found one of these nuts that needed to be cracked and it involved a simple search and replace, that I could turn around in my mind in anyway I wanted, but could not do it in a real situation. I could ask a guru for a quick solution, but then I would need to ask again every time I encounter something new. It was time to sit down and start learning.
The first problem I faced, that needed a bit more advanced approach to search and replace, was when I tried to start translating a freshly released version of some Linux application, but could not find a *.pot file. This *.pot file is nothing more than a text file with so called translation messages, where every string that is used by the program in the original language is matched with another string that needs to be translated.
