Is there any method to interact with a program directly from the commmand line?
For example, I've a program,
data.o, which produces a file
mydata.out and then I want to plot it with
I can open the plotting program with
gnuplot & and then I would like the shell to write somehow in this job/background shell I just opened
plot mydata.out. (
gnuplot is just an example, the question would be similar for executing some Macros or Hotkeys in every program I can open from the command line without leaving it).
