I only ever see a Mac about twice a year and it is usually for either networking issues or audio. And every time it drives me crazy because I type a command into the terminal and it says “Nope”. Actually what drives me crazy is that it takes me 20 minutes th find the bloody termina. Anyway, here is a list of OS X commands.
Now whats really good is that there are some other lists of commands at this site as well for Linux, XP/NT and Oracle and lets not forget the Cheat Sheets from a few weeks back.
