Notes on C, Unix and Scripting

About the Book

These are the notes I developed while teaching a very unusual course at Carnegie Mellon University over 10 years ago. The course was expected to provide first year Computer Science students with a quick introduction to C, Unix and Scripting. Most students only knew Java and did not know a low-level programming languages or scripting that are critical to succeed in upper level courses. Hence the notes that helped cover those topics, not in depth, but just enough to get by. Over the years, people have found these notes online and used them. Now I thought of assembling them together. This might help you learn some of these topics quickly, but you need to find other books to supplement if you need to get a deeper understanding of any of these topics. I plan to add more supplemental material to this book in the coming months and years. I hope I have attributed credits to any material I have used in the book or I will do so, as I find them. The book is not formatted at the moment, but will be in the future and you will receive free updates..

I have intentionally revisited the same topics again and again. As we revisit these topics, the reader will be able to reinforce them more. There can be some errors in book. I appreciate if you let me know by sending email to andyguna2@gmail.com. I hope you will find this material useful in getting a quick overview of C programming in UNIX, Shell and Perl Scripting and Assembly Programming and Basics of Systems Programming. You can find lot more material such as skills labs, programming labs and demo code at the old site http://www.cs.cmu.edu/~guna/15-123S11/. The site is not well formatted, but hope it is useful.
