In COR@L Lab we use Debian operating system. Debian is a GNU/Linux operating system. Linux handles hardware level operations, and GNU is on top of Linux Kernel and consisted of desktop environment, windows, text editors and all other applications. GNU is a recursive acronym and stands for (GNU is Not Unix). Even though it is not Unix (which was an operations system itself) it behaves like Unix. It runs like Unix. In this page you can find the frequently used Unix commands. We highly recommend you to find out your own tutorials/books/videos on web.
