Shell scripts save time and run very efficiently.

There are many great individuals that go out of their way to help users in need. I would like to thank all the users but that is very hard to do. Many people have very interesting points to make. But to say that people are not helpful is not a good one. If one does not know the answer to a certain question, we continue on, why give out information that will not help the users out. Someone that has been there generally comes through and helps out. Best Regards, Antonio __________________________________________ Yahoo! DSL ? Something to write home about.
