How to create a Script inside a program in the terminal?

Question

I’m looking to develop a script to automate some repetitive tasks I’ve been doing on the terminal. However. I can only create Scripts for Commands directly in the terminal, not for commands within the program.

How can I create an SH that will act within this program?

I understand your question, but in my opinion your approach is wrong.

I can not see your image and also Oce did not quote the programming language, but this was already a doubt of mine and I will record here an answer to who it may interest if the language is C or C++.

No scripts are created on executables, if system calls are used to directly execute commands.

For this there are some alternatives, the simplest is to use within the executable a call to system().

A banal example would be:

#include <stdlib.h>

int main (int argc, char *argv[])
{
    system(argv[1]);
    return 0;
}

Try passing some argument to the executable, example:

./binario "ls -l"

There are also other calls that do this with the use of popen() and pclose(), depend solely on the stdio.h.
