Execute handy

-e argument can be put multiple times. -p is mandatory if want to prevent that window instantly exit.

gnuplot -p -e "plot 'data' using 1:2 with line, 'data' using 1:3 with line"
\ -e "set xrange [0:100]" -e "replot"

Execute by script file

gnuplot -p script.gpi
gnuplot -c script.gpi

*.gpi seems to be recommended. https://stackoverflow.com/questions/5497889/is-there-a-standard-file-extension-for-gnuplot-files#10053805
