使用 Cron 运行 Python 脚本? [英] Running a Python Script using Cron?

问题描述

我有一个想要添加到 cron 的 python 脚本.

I have a python script that I'd like to add to cron.

该脚本对其具有 +x 权限.

The script has +x permission on it.

如何将其添加到 crontab 中?(比如说，我希望它每分钟运行一次).

How shall I add it to crontab? (say, I want it to run every minute).

重要提示:当我导航(使用 shell)到脚本的文件夹时，我无法使用./script_name.py"运行它；它不起作用.然而，当我使用Python script_name.py"运行它时，一切正常.

Important: when I navigate (using the shell) to the script's folder, I cannot run it using "./script_name.py"; it doesn't work. Yet, when I run it using "Python script_name.py", everything works.

推荐答案

从 cron 开始，您应该将脚本作为 script_name.py 运行，并且您的脚本满足以下条件:

From cron you should be running the script as script_name.py and your script meets the following criteria:

• 设置了可执行位
• 脚本的 hash-bang 设置正确，例如.#!/usr/bin/env python
• 它可以从 PATH 访问
  • 例如将它放在 /usr/local/bin/ 或 /opt/local/bin/ (并且它们可以被您的系统访问 PATH.)
  • Executable bit is set
  • The script's hash-bang is set correctly eg. #!/usr/bin/env python
  • it is accessible from the PATH
    • e.g. place it in /usr/local/bin/ or /opt/local/bin/ (and they are accessible to your system PATH.)

    如果满足这些条件，您应该可以在本地系统的任何位置以 script_name.py

    If these conditions are met, you should be able to run it from anywhere on your local system as script_name.py
