That way, I don't have a new gnuplot window popping up every 10 seconds. What I would like is for each successive call to that line to direct its output to the same gnuplot. The above seems to be working ok except for one thing: Each call to the cat | trpr | gnuplot line (bolded above) causes a new, separate gnuplot window to open. (I've tried piping tail -f output instead of cat output to trpr, but that would not work for some reason.) What I am doing is the following: cat'ing out the contents of an mgen () log file, piping that to trpr () (which processes the mgen results into gnuplot-readable format), and then piping that output to gnuplot.Ĭat $MGLOGFILE | trpr drec real auto X | gnuplot -noraise -persistĬat $MGLOGFILE | trpr drec auto X output $PLOTFILE & gnuplot -noraise -persist $PLOTFILE I had a specific question about piping data to GNU Plot as part of a bash script.
