It used to be possible to pipe commands to gnuplot: cat script.gp | gnuplot When I try this with gp5, gnuplot seems to ignore the input. I did not see any comment on this in the documentation either way. What behavior should I expect? Best, Ph. |

Piping commands to gnuplot works fine for me with gnuplot 5.0.0
running on OpenBSD 5.6. In fact, I often do this for visualization:
I've written a Tk/Perl program 'slider' which provides a GUI to walk
through a data set, and outputs gnuplot commands for visualization;
I use it via shell scripts like this one:
#!/bin/sh
slider --min 401.022164175591 \
--delta 1.00255541043898 \
--max 501.277705219488 \
--continuous \
--command-file ../Phi.rl1-4.3D-slider-gnuplot-template \
| gnuplot
For a standalone test:
% uname -a
OpenBSD copper.astro.indiana.edu 5.6 GENERIC.MP#0 amd64
% echo 'show version long' | gnuplot

That last command produced an X window with the plot.
What gnuplot version are you using, and on what system?

No, it doesn't work for me.
Here is the contents of my test script:
set t pngcairo
plot sin(x)
I invoke it like this:
cat script.gp | gnuplot > graph.png
When I use gnuplot 4.6 patchlevel 3 (which comes
with my distro), all is well. But when I use version
5, nothing happens - I simply get dropped into an
interactive session.
Mind you, batch processing works with version 5:
gnuplot5 script.gp > graph.png
is fine.
Here are the specifics:

Version 5.1 patchlevel 0 works on your test script. What are you seeing when the shell goes into interactive session? If I run gnuplot > graph.png as if the two sides of the command were treated normally (i.e., not one piped into another), the interactive part doesn't work because the visual output is sent to graph.png. How about something in your autoload .gnuplot file that might be causing problems. (Although I can't imagine what that might be.) Dan |
