Novell has teamed up with Charles Sturt University in Australia to offer what we believe is the first Masters Degree focused on Linux. The university decided to debut the degree because of rapid growth in demand for Linux training and expertise. The degree program includes obtaining Novell’s Certified Linux Engineer certification, including passing of the Novell Practicum exam. This is good evidence of growing interest in Linux by new entrants into the IT workforce, and the University’s choice to go with Novell in the curriculum is a nice vote of confidence.
file — Try to determine the FILE type. Summary : File tests each argument in an attempt to classify it. There are 3 sets of tests, performed in this order: File System Test Magic Number Test Language Test The File System test is based on examining the return from a stat(2) system call. The program checks to see if the file is empty, or if it’s some sort of special file (block, char, pipe, …).

Linux users can now boast of a better 3D desktop because of efforts from Novell. Novell is contributing a new graphics subsystem called “Xgl” and the associated “Compiz” compositing manager to the granddaddy of all Linux and UNIX windowing infrastructures, X.org.
