Today I tried using Mathematica's plotting capabilities to display the output of a C++ program. This made me wonder whether it is possible to somehow tell a Mathematica script to read from STDIN and then do something with that, a la
#/usr/local/bin/MathematicaScript -script (* Mathematica plotting script *) data = ReadStream["STDIN"]; plot = ListPlot[data]; Export[plot, ...];
which can then be used like
./cppDataGenerator | mathematicaPlotScript
However, I couldn't find much on that in the documentation, the entries always focus on output or string streams, and trial and error didn't yield a result either.
So the question is: How can I make a Mathematica script listen on the standard input?
