Peace,

I have written the following script which is to make a cycling calculations,

----------------
#! /bin/sh
set_P tb 05 MG 100
run 5 50000

set_P tb 06 MG 160
run 5 50000

set_P tb 07 MG 170
run 5 50000

set_P tb 08 MG 180
run 5 50000

set_P tb 09 MG 190
run 5 50000
.
.
.
.
.
set_P tb 70 MG 750
run 5 50000
--------------------
I know how to make a script which do the work if I have one running varaiable, but as you see here
I have two running variables. The first is called 'tb' and it runs from 05 to 70, say, with
a step of 1. The other is called MG and it runs the same number of steps but with a step of 10.

I know it can be done, would you please help me?

Thanks a lot,

PS.
I read a lot a bout shell scripting and I only found talks about doing one loop only. I have here two as you can see.

Would this be what youre looking for? Or did I understand incorrectly? (:

this is exactly what I dreamt with. Man, you are a genius!

Thank you very much

Another script I need is one which is capable of the following;

I have a code which gives me my results as column of numbers just like the following:
2
3
-8
9
57
5
34
.
.
.
-10

Is it possible to make a script which can take these values and put them in a table forum such that they form a second column, the y column, and get the form:
2 2
4 3
6 -8
8 9
10 57
12 5
14 34
. .
. .
. .
100 -10

the idea is that I want to add the first column, which runs in a controlled pattern (add 2 each step), to the results column so I can have a file with two columns which fits the gnuplot.

I hope I could make it clear

Do you mean you have a program that outputs the first set of data and you want to be able to format it without editing the first program?

you can pipe data from one program to another...

prog1 | prog2

prog1 would spit out the first set of data that would then be piped to prog2 through standard in. You can redirect input from standard in with the $< variable.

Alternatively, you could use the output from prog1 in the argv array like so:

prog2 `prog1`

Hope that answers your question.

Thanks for your answer.
I mean the program I have gives me the first column as an output. this is the colum which stands for the y-axis, say. I want to use these as a second column in a file such that the first column, which stands for the x-axis, is written just beside the column of results, the y-axis column, as in the example, so I can use a two-column file, one I added manully and the other which is generated by my program, to plot them with any drawing program.

You can do it with awk:

myprog | awk '{s+=2; print s,$1}'

Hi Lasse,

My code produces the results in a format which is not directly a column of data, but I can make that column easily, then i should do the job I mentioned above! Any solutions.

Thanks again all,
