I'd like to test a script by giving it an unreadable file as an argument.I usually log in as a user, but one that's in the Administrators group. I made the file (a text file containing just "hello") owned by user Administrator with absolutely no permissions for anyone else. In Windows Explorer, when running as Administrator, it says that mymachine\tmcdaniel has no permission on the file at all -- I can't even view permissions as tmcdaniel. In cmd, I get c:\home\tmcdaniel>type noperm Access is denied. c:\home\tmcdaniel>CACLS noperm c:\home\tmcdaniel\noperm Access is denied. though I can see some information in other ways: c:\home\tmcdaniel>attrib noperm A C:\home\tmcdaniel\noperm c:\home\tmcdaniel>dir noperm ... 04/30/2009 02:47 PM 6 noperm 1 File(s) 6 bytes But Cygwin lets me see it just fine. $ cd $ cat noperm hello and I can see the contents in vi also. So - how do I manipulate a file so that only the owner user can do anything with it, even in Cygwin, even if that owner user is in the Administrators group? - how is it that Cygwin gives more permission than Windows? I am using the latest Cygwin, just updated a few hours ago. Please let me know if you need more information.
It's a known fact that Cygwin allows users that are members of the Adminstrators group access to any file, regardless of it's permissions. This mirrors what an administrator can do in Linux. I haven't investigated a way to try to circumvent this, though I expect a successful attempt would be fragile. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
