looping and saving output of each line separately

I have been trying this program for a long time. I am trying to read a file named "odon" line by line; read the first line, send it to do a command saved in a file "perm", once the first line has finished going through the content of the file perm, the result is saved with the number of the line. Once that is done, the script reads the second line and repeats the process until all the lines have been read, sent to the other file and the output saved. This is what I mean:
Code:
12 1 1
2 1 1
3 1 1
92 1 1

read line 12 1 1, send it into file "perm" which contains a command, then the output is saved as beta. The next file as beta1, the next file as beta2 etc. The content of perm will output "beta" when it is read in the right way. I used only one 12 1 1 and it gave me beta, but to read each line and save with different names is proving difficult.
This is what I have done so far:
Code:
#!/bin/sh
for i in 'cat odon'
do echo $i | ./perm $i > $i
cp beta beta.$i
done

This does not seem to work as I want. I would appreciate your contribution. Thanks

What's in perm? Does it read from a pipe, or does it take a parameter? In the script as posted, it does both.

perm contains a program that runs automatically if done right. t contains something like itgen -m 500 -r rhs -b beta -n con.
I want each line to pass through perm and send out beta. The next line should be beta1 etc. I have tried it for just one line and it gave me beta
Thanks

It is impossible to guess what faulty script is intended to do. I repeat:

perm is a file name I just created and it contains a program whichI want each line to be read into. I just tried to pipe each line to perm. It may not be the right approach to take. The content of perm which automatically produce an output beta for one line of the file odon. My challenge here is to do each line automatically instead of having to manually work through each line

Whether it's the right approach or not really depends on what perm does. It might be the right approach. It might not. We literally have no idea.

Until you explain what perm actually does -- the input you feed into it and the output you expect from it -- we can't help you.

I just created a file and named it perm. It is the content of the file that is important because it contains a program we use in research. The program is: itgen -m 500 -r rhs -b beta -n con (I just created the file to save what I need). Its like doing a*b=c, the the program gets the value of b for you automatically. Each line must pass through this program and it will output b which in my case is beta. That means I have a file named rhs and another named con; but itgen -m 500 -r rhs -b beta -n con will run through each of this files by itself so I don't really need to bother about the files. The first line in the file odon (12 1 1) will pass through itgen -m 500 -r rhs -b beta -n con and beta will be automatically produced (I have tried it with just one line and it gave me beta so it works). My challenge is to take the first line and put it in the file I save as perm, produce beta, then repeat it for each line in odon saving beta as beta0, beta1 etc
