Standalone Mathematica Kernels
Mathematica's core language and computation capabilities cannot only be accessed through its rich interactive notebook interface, but also directly through a command-line interface—allowing Mathematica to be used in large-scale batch mode, or as the world's most powerful scripting language, fully integrated into any computational environment.
Command Line Programs
Mathematica, mathematica launch the complete Mathematica system
MathKernel, math launch a standalone Mathematica kernel
% most recent output expression
