Reply-to: tom dot quarendon at teamwpc dot co dot uk

Two issues as I see it. Firstly, cygwin doesn't appear to pick up that I have write access to the file README.txt. The getacl output below doesn't list Authenticated Users. I can't use vi to modify the file, but I can read the file using cat and so on.

Secondly, cp takes a source file that I can read and copies it to a target file that I subsequently can't read. This seems inconsistent. Clearly cygwin is taking notice of the access control list as well as the posix permissions when doing something like cat, as the README.txt file has no posix permissions, but I can cat it. However cp doesn't copy that access control list information so the target file only gets a copy of the posix permissions.

The file e:\wps2\dev5\README.txt has windows permissions:
Authenticated Users: modify, Read & execute, Read, Write
System : Full control, Modify, Read & execute, Read, Write
Administrators : Full control, Modify, Read & execute, Read, Write
Users : Read & execute, Read

$ type -a cat vi chmod
cat is /usr/bin/cat
cat is /bin/cat
vi is /usr/bin/vi
vi is /bin/vi
chmod is /usr/bin/chmod
chmod is /bin/chmod
