Ok, I got, they are different. But playing a bit more with glob, I found out
that (or, at least, it seems to):
Dir.glob("[EMAIL PROTECTED]/**") == Dir.glob("[EMAIL PROTECTED]/*")
and
(Dir.glob("[EMAIL PROTECTED]/**/*/**") | Dir.glob("[EMAIL PROTECTED]/**")) ==
(Dir.glob("[EMAIL PROTECTED]/**/*/**") | Dir.glob("[EMAIL PROTECTED]/*")) ==
Dir.glob("[EMAIL PROTECTED]/**/*")
Except for order. To be sure, try this:
(Dir.glob("[EMAIL PROTECTED]/**/*/**") | Dir.glob("[EMAIL PROTECTED]/*")).sort
==
Dir.glob("[EMAIL PROTECTED]/**/*")Dir.glob("[EMAIL PROTECTED]/**/*").sort
So, I would change my question:
Wouldn't
Dir.glob("[EMAIL PROTECTED]/**/*")
be a better replacement to
Dir.glob("[EMAIL PROTECTED]/**/*/**") | Dir.glob("[EMAIL PROTECTED]/**")
?
