Program to run as shim, for windows 10 clients who want to soft-bypass cmd checking from windows, their own scripts

dothat.py

#!/usr/bin/python3
#
# dothat.py (name it what your .cmd file is called, plus .py of course instead!)
#
# simple dirty program to launch a batch command (cmd) file of the same name
# but not same file extension, in the same directory
#
# to use: name this program whatever you're script is called, but use .py of course instead of .cmd
# 
# example: this file, saved as "dothat.py" when run from "c:\somewhere\dothat.py" will attempt to run
#          this command line:
#           c:\windows\system32\cmd.exe /c c:\somewhere\dothat.cmd
#
# notes:
#          this directory is first discerned from the path passed with argv[0]. If there is no valid path
#          it will fall back to the current directory specified by the operating system
#          if the filename.cmd cannot be found, it will simply return an error.
#
# return codes:
#
#   0   - executed OK (does not return error code of program, you will need to get this yourself) or tryexec_override was set to 1 (see below)
#   12  - failed, did not find filename.cmd, and tryexec_override was set to 0
#
# special variables
#
# tryexec_override  possible values: 0 = normal execution success and failures
#                                    1 = try execute even if file is not found, and return no error either way
