I am in an intro to unix/linux course, and need some help with a project. We are tasked with creating a basic script to automate a task that an Admin might need to do. We submitted ideas and mine was to have the system keep a record of log in and log out times for users. I thought this was going to be easy, it seemed like it, but the teacher said if I could pull it off I would get an automatic A and he was anxious to see how I do it. Now I'm worried I bit off a bigger chunk then was expected of me. If I change scripts now I will automatically lose points. I'm not asking for the script to be written for me, not only would I not learn anything but I need to give a description of each line of code and what it does. So really I'm asking if any of you Linux pros, I know you're out there, would either kind of walk me through it or at least send me to the right spot to learn this. My book for the class is for absolute beginners and I'm unable to locate the information necessary to really even begin this task. Any help would be very much appreciated. Even if you can't help thanks for taking the time to read the post.
