need help with understanding and modifying script

Shell Programming and Scripting
1

hi all,

i am new to UNIX. this is my first time using Ubuntu. i need to do this for my fyp.

i am using an artificial neural network model to predict the yield strength of steel. the shell script used to execute this model is as shown here:

when i run the program this is what shows:

i need to get rid of the disclaimer and i dont want the computer to ask to press return to continue or agree or ask display results. i just want it to run the program and give the results automatically. how shd i modify the attached file to achieve this? when i run the program it shd just show the following.

Can anyone help me modify the program to do this?

Your help will be greatly appreciated.

Thank you.

Contact with author of this code and ask him for help. He must agree before you could use that code. It seems to be Thomas Sourmail.

Hi Adderek,

I think your post may be out-of-line.

First of all, there is no copyright notice in the code.

Second of all, it says "use at your own risk".

So, I don't see anything that is illegal, wrong or unethical, unless there is a copyright that was removed.

Also, you are not a moderator here, so please post your concerns privately. Thank you.

On the other hand, if this post is homework, it may be a rule violation anyway.

hi all,

this is not homework. I just need help understanding the script because I have no knowledge or experience with linux shell scripting. my work involves the design of steels. But for me to do that i need to understand the script and modify it so that it would work with another program that i am using.

maybe someone would be kind enough to explain what is going on in the program so i can make the necessary changes. i have limited time and I would really appreciate all the help i can get.

Thank you very much. It will save me a lot of stress, if someone could help me with this. I have gotten this program from this website MAP Program Steel_YS

I am not violating any laws using this.

Just remove all the lines copied below

I'd be interested to know if the model works fine...
