I'm looking for a tool or method to find out what command line parameters have been passed to a program, for example when it was run by another program (launcher-application scenario).
You can do that using Process Explorer.
Just hover with your mouse over a process to see the command line arguments used to start it:
Alternatively, you can open the properties of the process and inspect the command line right there:
You can do it without Process Explorer, too, using Windows' WMI service. Run the following from the command prompt:
If you want to dump the output to a file (makes it a bit easier to read), use the /OUTPUT switch:
When using CygWin, if I start a Python process, this is an example of command line:
But Process Explorer only sees the main exe:
(note the "path: [Error opening process message]").
Same results for
So, the only trick I know until now, is finding it via CygWin Bash shell
It is useful to know this, as long as CygWin cohabits with no problems in Windows, and you can use it to run many POSIX and Python programs.
EDIT: In Windows you don't seem to need administrator priviledges for tasklist. In CygWin you will need them to be able to view an administrator's process (what seems more logical to me: the full command-line could have some parameters like passwords inside), so we must run the CygWin Bash in elevated Administrator Mode.
