int main(int argc, char * const *argv)

    ret = fork();
    if (ret < 0) {
    
    
        printf("Failed to fork for shell\n");
    } else if (ret == 0) {
    
    
        (void)execve(shellPath, NULL, NULL);
        exit(0);
    }

    while (1) {
    
    
        ret = waitpid(-1, 0, WNOHANG);
        if (ret == 0) {
    
    
            sleep(1);
        }
    };
}

代码很简单，知识点execve waitpid
