plot is not generated (gnuplot from command line)

Question

In sample.dat I have:

set terminal pngcairo  transparent enhanced font "arial,10" fontscale 1.0 size 500, 350 
set output 'simple.2.png'

plot [-pi/2:pi] cos(x),-(sin(x) > sin(x+1) ? sin(x) : sin(x+1))

From ubuntu/terminal I execute:

gnuplot -e "filename='sample.dat'"

but the simple.2.png file is not created. How do I export a plot to e.g png using gnuplot from command line?

I have no idea where you got that from!

To execute a gnuplot script (here called simple.gp), simply call

gnuplot simple.gp

You should keep the extension .dat for data files.
