Eric V. Smith added the comment: In the first example, you switch from "./app" to "app.exe" when using shell=True.
What happens to any of your examples if you add ".exe" without shell=True? Popen eventually calls CreateProcess on Windows. From: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx, describing the lpApplicationName parameter: "This parameter must include the file name extension; no default extension is assumed." Running the shell though, you don't need the extension. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20927> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
