I've posted to this effect before, but normally you can capture the output from terminal commands with ReadList or Import which provide various possibilities for parsing it. Try Import["!dir", "Text"] (on Windows) ReadList["!dir", Record] (on Windows) Import["!ls", "Lines" ] (on Unix-like) ReadList["!ls", Record] (on Unix-like) The exclamation mark is essential to distinguish the command from a file name.
