A dictionary of Unix commands

Unixes (Unices) are largely consistent – at least that’s been the theory. But if you’ve ever wrestled with the differences between lp and lpr (hint: BSD vs. SystemV) or tried to remember at least the right general command to do something, a reference like this is gold.

That said, Caveat Emptor: this is not an exhaustive guide. It’s a way to prod your memory or help you find something new, which you’ll have to explore and learn in depth on your own. In other words, SOP.
