It looks like `ls(1)` for Win32 calls the `GetFileInformationByHandle` function[1] when it checks file modes. Therefore, it operates by file attributes (`FILE_ATTRIBUTE_READONLY`, `FILE_ATTRIBUTE_DIRECTORY`, etc.), which don't affect users in the file's group (g) or other users not in the file's group (o). The similar stuff is applied to `chmod(1)`.
The security descriptors in Microsoft Windows have ``primary group'' information, which, I believe, exists there for compatibility with POSIX, but GNU's coreutils don't use it. May be because that ``primary group'' exists only on NTFS. > $ ls -l csv.icn > -rw-r--r-- On Win32 ``rw-'' stands for ``file without read-only attribute''. It looks like `r--` for ``g'' and ``o'' is a default for `ls(1)` on Win32 (but I'm not sure, because I didn't find that in source code). > $ chmod 775 csv.icn The only thing you can make with `chmod(1)` on Win32 is set ``Readonly'' attribute with `chmod u-w csv.icn`. Operations with ``g'' and ``o'' are effectively ignored. May be I'm wrong somewhere; in this case I hope someone will correct me.
