Shell Programming and Scripting

Please help me decide if I'm doing the write thing by writing a "shell script" to automate running this program that I can run from my command line with no problem. I've tried all your suggestions but none worked out. Should I use something else other than shell scripting?

Thanks

If You can run the program from the command line, You can most certainly run it from within a script. But Your description is still a bit unclear. I get the impression that You want to be able to be prompted for the parameters before You "send" them to s2, is that correct?

Ok let me try to rephrase my question

The program s2 can be run in command line by typing:

>s2 param1=val1 param2=val2
>enter value of param3: val3
>enter value of param4[2000] ;return key accepts default
> ...................

Now from within my shell script I did:

param1= val1
param2=val2
param3=val3

s2 param1=$param1 param2=$param2
echo $param3
echo -e '\r'

the program runs but with errors as it doesnt get the values of the params I feed it through my shell script correctly

The echo in your code will only run when s2 finishes. To provide $param3 as input, try this instead.

Code:

s2 param1=val param2=val2 <<HERE
val3

HERE

Whether it works or not depends on whether s2 accepts the remaining parameters as standard input; some programs explicitly read from the terminal, or use some sort of interactive front end which doesn't work with standard input.

Thanks so much!! Now that I realized when the echo is executed, it works !!!
Thanks again

If you know how to pass parameters to a FOTRAN file. then hust call the obj file from you script. and pass the args to the object file.
