Using POSIX = is preferred for compatibility. In bash the two are equivalent, and in sh = is the only one that will work. In physics, particularly in quantum field theory, configurations of a physical system that satisfy classical equations of motion are called "on the mass shell" or simply more often on shell; while those that do not are called "off the mass shell", or off shell.
