I have been working on a python script that I want (NEED) to run as a scheduled task on a remote machine. I got to the point that the script did exactly what I needed when I was interactively running it in a Windows session but had problems when running it as a scheduled task. The debugging process was cumbersome–make a change, schedule a task to run it, log out of the machine, and wait. The log back in and repeat the process.
That got old.
So I wrote a script (tester.py) that calls any other python scripts in the same directory that (1) start with “test_” and (2) there is not a corresponding file with the same base name and “.start” extension. It would launch “test_BaBing.py” as long as there is not a “test_BaBing.start” in the same directory. Tester.py continued to run, looping every 60 seconds, until tester.stop exists.
This made the process easier because I could work on my local machine, editing the problematic script, saving changes and within 60 seconds it would be launched on the remote machine. I could view the results, make additional edits, delete the .start file and it would launch again within 60 seconds.
Within a couple minutes I was able to determine the problem (path related) and fix it.
<disclaimer>I would recommend using this only while debugging a script–routinely running it could be a security risk since someone could copy a destructive python script into the directory and this would run it.</disclaimer>
