By "command line," I take it you mean when the shell is interactive. The answer is essentially the same, a positional parameter or all parameters (for $* or $@) are substituted in place of the variable reference. Interactive shells usually don't have positional parameters, but they can. Just as with any other shell, they can be passed when the shell is launched or can be established (and changed) later using the "set" built-in.
