Have you cleaned up your Linux installation lately? On its face, that question might wrongly mark me as a Linux newbie, much like a Linux newcomer asking about antivirus and antimalware software. But I am far from being a newbie to Linux. That said, three program packages designed to clean out your Linux dustbins can keep your OS working like new. I admit that sounds like a sales pitch hawking some must-have maintenance tool for Microsoft Windows. But BleachBit, GtkOrphan and Startup Manager can give you more control over how your Linux distro behaves.
