Question

I have some problems with the following:

I would like to plot many data files, and I found a more or less good script for that

#! /bin/bash
ls *.data | sed "s/.data//" > list
for i in `cat list` ; do
   sed -e "s/INPUTFILE/$i/" -e "s/OUTPUTFILE/$i/" \
    plot.gnu | gnuplot
done
rm list

plot.gnu

set term postscript enhanced color
set output 'OUTPUTFILE.eps'
set title 'OUTPUTFILE'
p 'INPUTFILE.data' u 1:2 w l

But I have problem with this part

for i in `cat list` ; do
       sed -e "s/INPUTFILE/$i/" -e "s/OUTPUTFILE/$i/" \
        plot.gnu | gnuplot
    done

somehow it cannot update the plot.gnu file as it should be… This sed command does not work properly…

Can anyone help me to solve this issue? Thanks in advance!

Answer 1

Let’s try

for i in `cat list` ; do
   cat plot.gnu | sed "s/\(INPUTFILE\|OUTPUTFILE\)/$i/g" | gnuplot
done

Cheers
