I find it odd that the single most important command is absent from the list: man (w/ -k, or apropos). The article could really do with a section 0 to explain it. Armed with the ability to actually find commands and RTFM, you don't need to try and remember stupid lists of commands. Obviously it's helpful to remember commands, particularly frequently used ones - but you should start with the right mentality: that of being able to use your initiative to work something out, rather than resorting to google and not having to think.
