Couple of days ago a friend of mine pointed me to commandlinefu.com. It’s strange how addictive a service like that can be! I’ve perused a good chunk of the commands posted on the site, learned quite a few new things, augmented the command aliases on my servers, and posted few of my brainchildren as well as posted suggested fixes to some that I found to be a cool ideas but that didn’t work for me as they were presented (such as the command to copy database from a local MySQL server to a remote MySQL server over SSH).
