• command() is a small but powerful FOSS C++ function.
• Its formula is basically: system()-like syntax + fork()/exec() safety = command()
• Designed to provide an easy, readable, shell-free way to run system commands.

While developing my project pacostrap, I realized:

• system() is too risky due to shell injection.
• fork() and exec() are safe, but painful to read and write.

So I wrote my own wrapper — command() — a minimal, readable and safe way to execute commands.

#include <iostream> // for cout, main, return function
#include <string> // for string valuable
#include "command.hpp" // for my own super duper awesome command function
int main() {
    std::cout << "Enter directory:\n";
    std::string directory;
    std::cin >> directory;
    command("ls -a " + directory);
    return 0;
}
