Akshay does a great job of giving you the ~100 or so key commands in Linux that you will need to get around. The fact that they were kind enough to not include ads is a major plus. Some suggested improvements might be to include the option to click the command example and see more detailed descriptions (i.e. some more info on commands within editors like vi) There are some minor typographic errors that should get fixed like the misspelled "locate" command. Altogether this is one of the cleanest, most straightforward command references on Play.
