This is a series of cornerstone articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems.
You’ve moved over from Windows or Mac OS X to the wonderful world of Linux. You’ve selected a Linux distro (after a bit of fruitful distro hopping), chosen a desktop environment, and studied the basic Linux commands. Now you want some really useful free applications. Well this article picks the finest open source software to help you manage your system.
The series examines both graphical and text based open source utilities. There’s a wide range of software we’ve recommended. There’s genuinely useful utilities, productivity software, networking, backup, monitoring, system cleaning and much more. All to download for nothing.
