The following page partially addresses this:
http://www.cygwin.com/cygwin-ug-net/ntsec.html
It says that:
--------------------------
If another user (or a Windows group, treated as a user) is not present
in /etc/passwd, the uid of that user will have a special value of -1
(which would be shown by ls as 65535). The user name shown in this
As we discussed earlier, -1 is now a 32-bit value, so shows up as
4-billion-something rather than 65535 these days, but apart from that this is
what is happening.
case will be '????????'.
--------------------------
I would like to modify the /etc/passwd file so that it shows me
as the owner of these files instead of '????????'.
No, you don't want to do that. You only want it to show you as the owner of
those files if you actually *are* the owner of those files, and the way for
that to happen is for your user account in the windows domain to actually be
the owner of those files, and to be linked to your cygwin uid/gid via the
/etc/passwd file.
Do you *actually* own the files? What kind of drive is this; network or
local? NTFS or FAT?
This is a second drive in my XP system. The drive contains all of my
data. One of the folders/directories on this drive is what I use
as my home directory. It has an NTFS filesystem. I map my home
directory on this drive to a drive letter so it shows up in
Windows Explorer as a mapped network drive even though it is a disk
physically on the same system. This is a relatively new disk
(and computer). I copied my all of my data from my previous computer
onto this disk in this new computer.
I've always thought that I actually owned the files. The Windows
security tab says that I own them. It wasn't until I installed
Cygwin that I had any reason to believe otherwise.
I see that I can do a "chown -R wes" on a directory and it makes
me the owner as far as Cygwin is concerned. Windows Explorer
says that I am the owner before and after doing this. I can do
this to fix all of the files. It's just a bit curious to me that
Cygwin says I am not the owner but Windows does.
cheers,
