Jan-Philip Gehrcke added the comment: 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. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue23427> _______________________________________
