python - 在特定时间打开文件。 C ++ / Python(Open file at specific time. C++/python)

Question

I have .sh file on my macOS Catalina.

(我的macOS Catalina上有.sh文件。)

I would like to open it at eg 1 PM (I need accuracy).

(我想在下午1点打开它（我需要准确）。)

So, I have already tried crontab, but something goes wrong, and I can't do it.

(因此，我已经尝试过crontab，但是出了点问题，但是我做不到。)

So, Is it possible to make a program on C++ or Python to open a file at specific time?

(那么，是否可以在特定时间使用C ++或Python编写程序来打开文件？)

I have some skills in C++, but as I know there are no libs with reading current time, maybe I wrong?

(我有一些C ++技能，但是据我所知，没有库可以读取当前时间，也许我错了吗？)

I haven't any knowledge in Python, but is it possible anywhere?

(我对Python没有任何了解，但是在任何地方都可以吗？)

Thank you!

(谢谢！)

UPD:

(UPD：)

int main() {
    struct tm *tim;
    time_t tt = time(NULL);
    tim = localtime(&tt);
    while(!(tim->tm_hour==** && tim->tm_min == ** && tim->tm_sec == **)) {
        tt = time(NULL);
        tim = localtime(&tt);
    }
    system("...");
}

Looks like a bad idea, but it works...

(看来是个坏主意，但确实可行...)
