A sidenote: LinuxQuestions.org is a community of people that are spending their free time to help other people with their Linux related problems. We are not paid to do this, all of us are volunteers. Demanding urgent help is considered rude here (especially when it comes to homework questions) and will drive people away from reading your threads. Normally you yourself should be able to solve those questions, if you have followed your course and read the provided material. Of course we will help you if you have problems to understand the material (although the first way should be to ask your teacher for better explanations), but we will not do the work for you. Show us what you have done already and where you have problems, that way you will learn more.

Moved: This thread is more suitable in Linux-Newbie and has been moved accordingly to help your thread/question get the exposure it deserves.

Please use a descriptive title for your thread excluding words like 'urgent' or 'help'. Using a proper title makes it easier for members to help you. This thread has been reported for title modification. Please do not add replies that address the thread title.
