Start new mac terminal window with new process

Question

I'm using fork() to create new process.

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
#include <ncurses.h>
#include <iostream>
#include <time.h>

int main (void) 
{
    switch (fork())
    {
        case -1: exit(0);
        case 0: {
            execl("Terminal.app", "shell", "-e", "time ls; shell", (char*)0);
            break;
        }
        default: {
            std::cout << "OK" << std::endl;
            initscr();
            time_t secs = time(NULL);
            tm* timeInfo = localtime(&secs);
            printw("TIME: %s", asctime(timeInfo));
            getch();
            endwin();
        }
    }   
    return 0;
}

This code should create new console window and make time ls, but it doesn't. What is the problem?

What does it do? Have you tried calling open -a Terminal.app instead of just Terminal.app? — Richard Barber

Use the command open -a -n Terminal.app to run a new instance of the app (even though one is already running).

rly? I wanna do this from my c++ program, not from console.

Yes, don’t use the name of the app container to execute it. Use open.

You’ll have to parse it to suit

Just in case anyone else runs across this answer, I needed to change the command to open -n -a Terminal.app to get it to work. I also referenced ss64.com/osx/open.html.
