UNIX Shell Programming

In an environment that has a large number of desktops/servers to maintain, or in a heterogeneous environment, system administration certainly becomes a complex task. System Administrators will need to develop and customize their own automation tools in order to address the leverage of time and resource requirement of this task. This course covers everything needed for the ultimate system administration automation right from creation of customized commands to the development of complex self-maintaining autonomous systems.
