Linux is now the world's dominant Internet server platform: from Google to Amazon, it's at the heart of the world's most sophisticated technical infrastructures. As a result, more technical professionals need to be proficient with Linux than ever before. It's not enough for them to navigate a graphical user interface: real power comes only from the command line and Linux's massive collection of command line utilities. For years, Mark G. Sobell's A Practical Guide to Linux Commands, Editors, and Shell Programming has been the gold standard reference to the Linux command line and utilities. Compact, concise, comprehensive, and distribution-agnostic, it's packed with carefully-constructed real-world examples and clear explanations focused on Linux's most useful utilities and options. Now, Sobell has thoroughly updated this indispensable classic to cover even more of Linux's best tools, and to offer complete primers on Linux's leading database (MySQL) and scripting language (Python).
