int main(int argc, char* argv[])
{
	int fd = open("tmp.txt", O_CREAT | O_APPEND | O_RDWR, 0666);
	char buf[] = "hello huang jia jia\n";
	write(fd, buf, sizeof(buf));
	close(fd);
	sleep(8);
	if(fork() == 0)
	{
		if(execl("a.out", NULL) < 0)
		{
			perror("Execl:");
		}
	}
	return 0;
}

关闭进程命令:ps l | grep out | grep -v grep | cut -d' ' -f6 | xargs kill -9
