I handle that with two variadic functions (arguments are stringified and spaced): template <typename... A> int shell(A... arguments) template <typename... A> string execute(A... arguments) shell() does a system() and returns the exit code (so the output is echoed in the terminal). execute() launch a process with popen() and returns the captured steam as a string. About capture of stderr with fork(), I like the way it's done in Node.js: https://nodejs.org/api/child_process.html https://nodejs.org/api/child_process.html shell: https://github.com/vmorgulys/sandbox/blob/master/stackcity/source/core/i.function.shell.cpp https://github.com/vmorgulys/sandbox/blob/master/stackcity/s... pfile: https://github.com/vmorgulys/sandbox/blob/master/stackcity/source/core/class.pfile.cpp https://github.com/vmorgulys/sandbox/blob/master/stackcity/s...
