问题描述

我想知道如何确定是否从crontab执行python脚本？

I would like to know how can I determine if a python script is executed from crontab?

我不想要一个解决方案，需要添加一个参数，因为

I don't want a solution that will require adding a parameter because I want to be able to detect this even from an imported module (not the main script).

推荐答案

不是您要求的内容，但也许你想要的是 os.isatty（sys.stdout.fileno（）），它告诉 stdout （大致而言）连接到终端。如果将输出传递到文件或另一个进程，或者从cron运行进程，则它将为false。

Not quite what you asked, but maybe what you want is os.isatty(sys.stdout.fileno()), which tells if stdout is connected to (roughly speaking) a terminal. It will be false if you pipe the output to a file or another process, or if the process is run from cron.
