POSIX rules are simply to search PATH for the filename as passed, and if it has a slash in it, the path is resolved against the working directory. There is no implicit search of the application directory, current directory, and system directories. There is no search for "dir/file" in *every* search path directory instead of just resolving against the working directory. There is no figuring out when ".exe" or PATHEXT extensions will be appended or how to search for a filename that has no extension by appending a trailing "." to the name. And there is no massive inconsistency between the search semantics of shell=True and shell=False. What happens with "platform semantics" in Windows is complicated compared to POSIX. I'm more comfortable telling people to search via shutil.which() than relying on the platform search. I'd be much more comfortable if that's what subprocess.Popen() just did on its own. But we're locked into platform semantics, and I don't see that changing. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42041> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
