Many books have been written about strategy, tactics, and great commanders. This is the first book to deal exclusively with the nature of command itself, and to trace its development over two thousand years from ancient Greece to Vietnam. It treats historically the whole variety of problems involved in commanding armies, including staff organization and administration, communic...(展开全部)

The most basic interface to a computer—the command line—remains the most flexible and powerful way of processing data and performing and automating various day-to-day tasks. Command Line Fundamentals begins by exploring the basics, and then focuses on the most common tool, the Bash shell (which is standard on all Linux and iOS systems). As you make your way through the book, you'll explore the traditional Unix command-line programs as implemented by the GNU project. You'll also learn to use redirection and pipelines to assemble these programs to solve complex problems. By the end of this book, you'll have explored the basics of shell scripting, allowing you to easily and quickly automate tasks.

Commanders at sea struggle not only with the unpredictability of natural elements, but also with a shroud of uncertainty often referred to as the "fog of war". Over the centuries, most admirals yielded to the natural temptation to find in new technologies a means to assert centralized control over their forces. But other commanders have recognised the fog for what it is: a cons...(展开全部)
