[FIXED] Detect within IPython which CMD/Terminal call was used to start IPython

Issue

Suppose that I start IPython with the following command in the Windows 10 CMD:

 "C:\MyFolder\ipython.exe" -i --matplotlib=qt5 --InteractiveShellApp.exec_lines="['import numpy as np']"

From within the IPython console that is initialized, is there a way for me to find exactly which command was used to initialize the IPython console (which is the above)?

If not, is there at least a way to retrieve the part "C:\MyFolder\ipython.exe", that is the exact path to the currently run ipython file?

Solution

The information you're requesting (raw program arguments as passed - say - to a C program with main(int argc, char *argv)) is not available at the python interpreter level (a more complete - but partial because it doesn't address python command and switches - explanation is provided in How do I find the exact CLI command given to Python?)

sys.argv provides the arguments that you're passing to your script, including the script itself as sys.argv[0], but not the python command line switches.

One thing you can get, though, is the executable which was launched: sys.executable

So the closest you can do is:

args = [sys.executable] + sys.argv
