[Gnuplot-info] redirection of Gnuplot output/errors

[Szymon P. <szy...@gm...>]

Hi everybody,
I have problem with redirection of data printed by GnuPlot to terminal
when working in batch mode. I have a bash script generating and
invoking GnuPlot's scripts. On terminal (STDOUT and/or STDERR) I need
bash script's messages, not fitting parameters.
I've tried
gnuplot script.gp 2>&1 > gnuplot.log
but it haven't work

I was looking at google, but I didn't find out any helpful informations :(
I will be very grateful for any idea or research direction.

Szymon

See "help set fit" and "help environment" for how to redirect the fit 
log to another file.

Of course it didn't.  And it's got nothing to do with gnuplot, either. 
It's a question of Bourne shell.  The correct sequence is

	gnuplot >gnuplot.log 2>&1

See "info bash basic redirect" for the details.
