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
