re-executing self with different arguments

[Gribouillis]

what i am wanting is to determine whether the script was run directly or if the name or path to the engine was used.

I don't think you can do that from inside the script. On the other hand you can get the pid of the current process and probably use a module such as psutil to find the command line associated to this process if any.

import psutil
print(psutil.Process().cmdline())
