One of the first basic steps in Unix administration is to master the Unix commands within the Unix shell. I’ve created a cheat sheet which summarize the essential commands you’ll need to get started. Most commands can accept a variety of parameters (switches); I have listed one or two most common parameters here. To look up the parameters and manual pages, use “man [command]” or “info [command]”.
