The question is: How should exactly look the AT command to schedule a one-time task to be executed by python. Here is what I tried:
at 20.00 "cmd python e:/path/to/file/script.py"
at 20.00 c:/Python27/python.exe e:/path/to/file/script.py
Neither is working, please advice. Command line example is required, can't use Scheduler Wizard on this one.
From the docs
time: Use this parameter to specify the time when the task is to run. Time is specified as hours:minutes based on the 24-hour clock. For example, 0:00 represents midnight and 20:30 represents 8:30 P.M.
So the time format you're using 20.00
is incorrect, and should be 20:00
.
