Why Ubuntu 16.04 C++ program cannot programatically stop mono-service?

[Karl Auer]

Oh for goodness' sake.

Create shell.cpp:

#include <stdlib.h>
int main (int argc, char *argv[]) {
    system(argv[1]);
    return 0;
}

Create a script called script.sh:

#!/bin/sh
ls

Compile shell.cpp into a program called shell:

c++ shell.cpp -o shell

Run the new program with a complete shell command, including
redirection (note the double quotes!):

./shell "./script.sh > /tmp/out.txt"

... and you will see the output from the script in a file in /tmp,
after the script has been run by the C++ program.

Why? There is no need to write extra programs. Linux has at least four
built-in ways to do EXACTLY what you want, and all of them have been
described to you. You have also been given several profitable lines of
enquiry via google searches.

There are also numerous systems/programs for running things as services
and logging their output. Check out supervisor, for example:

   http://supervisord.org

Writing your own program to do it is a total waste of time unless done
as an educational exercise.

This mailing list is about Ubuntu. It is not about writing C++. Please
find a C++ forum to help you with your programming problems.

Regards, K.
