How to plot and save many data files in GNUPLOT, inside a loop in a SHELL SCRIPT

[alice06]

Hi all
I badly need some help...

I plot a file output1.txt in the following way ::

gnuplot> plot "output1.txt" using 1:2 with lines, \
plot "output1.txt" using 1:3 with lines

BUT now I have many data files,

output1.txt, output2.txt, output3.txt, ...,... ,output1000.txt

I need to plot each one of them in gnuplot, and save them respectively in

graph1.jpeg, graph2.jpeg, graph3.jpeg, ..., graph1000.jpeg

It is very cumbersome if I plot and save 1 file at a time.

Is there an easy way, using loops in a Shell script that can PLOT and SAVE them

Please kindly help
Regards
Alice

StackOverflow has some very good answers related to this:
https://stackoverflow.com/q/14946530/8387076You can write your code like this:
[CODE title="Gnuplot"]set terminal jpeg
do for [i=0:50] {
outfile = sprintf('graph%d.jpg',i)
set output outfile
plot 'output'.i.'.txt' using 1:2 with lines, 'output'.i.'.txt' using 1:3 with lines
}[/CODE]
