Answer 1

You can run gnuplot directly with

gnuplot  

The environment opens in the console and you can add your commands after gnuplot>

load 'file.gnu'

If you're not in the same directory, you have to go there before or specify the path for the file.

You can have a look at this tutorial and here are some examples.

gnuplot -p somefile.gnu  > /tmp/sss.pdf
