Re: Problems with file permissions and cp when running on Vista

I'd start at the source. Give yourself POSIX-style access to the files
to start with. 'cp' will preserve that access. 'cp' and many other
utilities don't take ACL permissions into account. They are silently
ignored. For whatever reason, it looks like your source file has no
POSIX permissions for user, group, and other. Fix that with 'chmod'
and I think you'll have solved your problem.
I struggle to give myself posix style permissions.
I have a file README.txt in the root of my build source tree:
$ getfacl README.txt
# file: README.txt
# owner: Tom
# group: None
user::---
group::---
group:SYSTEM:rwx
group:Administrators:rwx
group:Users:r-x
mask:rwx
other:---
If I then do chmod --
$ chmod 755 README.txt
chmod: changing permissions of `README.txt': Permission denied
I can't modify the file with VI, but I can CAT it, so cygwin thinks I've
got read access to the file somehow. Copy the file and I get no
permissions at all.
I do have write access to the file though as far as windows is
concerned. If I look at the security properties of the file from Windows
Explorer it looks as though I'm getting write permission on the file
because I'm a member of "Authenticated Users" and that has write access.
"Authenticated Users" doesn't appear in the output from getfacl. Maybe
that's my issue.
So I'm not sure how I set myself up with correct posix permissions on
this file so that CP will work.
If suggestions others have made already don't help, I'd recommend falling
back to <http://cygwin.com/problems.html> if you need more help from this
list. Right now, I'm not really sure what file-system you're working with
and the tools in use. The 'cygcheck' output that the link above recommends
*attaching* to problem reports will help clarify some of these questions.
I'd also like to see the output of 'type -a cat vi chmod'. In addition, it
would be helpful to know what directory you are in.
