Victor, I support the idea of sys.command. However, it would be unpopulated most of the time (e.g. set to None by default). Now, is that something we should push forward or not? I would work on a patch, but we should have an agreement first, I guess. Mihail, the original argv becomes modified in the very early bootstrap phase, and the command gets lost within that process: it gets overwritten with "-c", which is exactly why you are observing two "-c". This happens here: https://hg.python.org/cpython/file/default/Modules/main.c#l684 So, no, without a code change in main.c there will be no way to retain the command for later usage.

Mihail,

the original argv becomes modified in the very early bootstrap phase, and the command gets lost within that process: it gets *overwritten* with "-c", which is exactly why you are observing two "-c". This happens here:

https://hg.python.org/cpython/file/default/Modules/main.c#l684

So, no, without a code change in main.c there will be no way to retain the command for later usage.
