Linda,
I saved your script as "lsacl.txt". Then I used "cp lsacl.txt it" to
make a copy.
The copy is permission denied for reading. Basic ls -l shows no
difference (as expected)
$ ls -l lsacl.sh it
----rwx---+ 1 gaf None 1630 Sep 24 12:05 it
----rwx---+ 1 gaf None 1630 Sep 24 12:00 lsacl.sh
But your script does show a difference:
$ ./lsacl.sh lsacl.sh it
[u::---,g::---,g:root:rwx,g:Authenticated
Users:rwx,g:SYSTEM:rwx,g:Users:r-x,m:rwx,o:---/] lsacl.sh
[u::---,g::r-x,g:root:rwx,g:Authenticated
Users:rwx,g:SYSTEM:rwx,g:Users:r-x,m:rwx,o:---/] it

Well user 'gaf' (that's you, from the file perms has no access).
So up front, you are denied before anything happens.
Totally logical, but not accurate. )
I am the owner of both "it" and "lsacl.sh."
For both the user permissions are "---" (why I don't know. I created
lsacl.sh by a simple drag and drop out of firefox.)
I can cat out "lsacl.sh", but not "it".
I know "chmod +rw it" gives me access to the file. The problem is
Windows is creating files with permissions like lsacl.sh routinely on
my system.
Then when I do anything to them in cygwin, the permissions are
modified to block my access.
I first noticed this because I was exporting CSV files from excel,
then editing them with vi from cygwin.
On the first edit, all was good. After that, I no longer had
permission to access the file.
So, either:
- Windows 7 (on 2 different machines) has started using default
permissions that are bad on their face
- cygwin is not properly maintaining the permissions when it manipulates a file
Either way, I would really like a solution that doesn't involve a
manual chmod for every file I create via the normal Windows interface
and which I want to work with it in cygwin.
The problem could be caused by the default ACL on whatever directory
you're working in. You might consider running 'setfacl -b' and/or
'setfacl -k' on that directory. (Run 'setfacl --help' for more
information.)
