[Gnuplot-info] command line variables into script?

[Gareth W. <g.w...@sh...>]

Hi all,

I have the following gnuplot script which takes data from a file with a single column and produces a histogram.  I will have to run this script lots of times, on different results files.  Is there a way to change 'res.dat' and 'res.eps' to command line variables so that I don't have to edit the script each time I run it on a different results file?  

Thanks in advance, 

Gareth


set terminal postscript eps
set output 'res.eps'
set boxwidth 1
bw = 1
bin(x,width)=width*floor(x/width)
set xrange [0:100] 
set yrange [0:50]
set xtics 5
set ylabel "Number of students"
set xlabel "Final grade"
set nokey
plot 'res.dat' using (bin($1,bw)):(1.0) smooth freq with boxes
