From OSFaq: “If you are like me and have to deal with a lot of different platforms you know how it becomes such a headache to remember every little minor difference between each system. While Unix is Unix, each system has slight differences in configuration file names, command parameters, etc that can drive you nuts when you switch between each system. Thanks to Joe Leogrande, we now have a nice concise table of equivalent commands and config file names for each platform. Plus the table can also be used as a command and config file reference with a short description next to each command. I highly recommend printing it up and making it part of your documentation.” The HTML version of the sheet can be found here.
