So, don't pull the cork.
Look, Bart, in a Unix shell, the user has the option to enable or disable
globbing (that action that converts the argument * into a list of files). A
Unix shell can give a program exactly the same list of unaltered arguments
that a Windows shell can.
But, point of fact is that the feature to disable globbing is not often
needed. Most Unix programs that accept filenames are happy to accept a list
of filenames. There is not much call for a program to perform it's own
globbing, like is required in Windows.
In fact, I can only think of three Unix "commandline" programs that need shell
find - which performs it's own filename matching
grep - which uses regular expressions to search the contents of files, and
sed - which uses regular expressions to edit the contents of files.
(I'm sure that there are a few more examples, though).
If your argument is with Unix shell globbing, I say that you can disable it.
If your argument is with Python's use of the default shell options to parse
commandlines in the Popen() method, then you need to talk to the authors of
Python to see if they can give you a way to alter this behaviour.
Otherwise, you are just being cranky and argumentative. Stop it. Suck it up
and move on. The world doesn't revolve around BartC, no matter how loud he
