Calling External Programs
Mathematica immediately allows you to call both standalone programs and individual functions or methods within running programs. Mathematica's architecture allows external functionality to be represented in a symbolic form that can immediately be manipulated within Mathematica—and that often makes access to external functionality from within Mathematica more convenient even than from its own native environment.
Run run an external command-line program (!prog to run as a shell escape)
RunThrough feed standard input to an external program, and capture output
