Hallo Benoit,

I see, sorry.

$ [ -x .patch ]; echo $?

$ perl -e 'print -x ".patch" ? 0 : 1 , "\n"'
0

Hmm, the file is mine, I'm the domain-admin, I get '0', your file is
owned by Administrastor and domain user is the group, you're not
Administrator so you get 1 from this perl snippet, what is wrong about
this?

Well, you said you still can execute bash.exe, test reports it as
executable.  Since Windows ACLs are very fine grained you may have the
permission to execute it, regardless what Cygwin ls displays , there
is just a subset of the windows ACLs displayed, e.g. a file may be
accessed by several groups and you may set the ACL different for each
group.

What are the bash.exe permissions beyond what ls is displaying?  Which
Windows version do you use?  What says getfacl about your bash.exe?


If I login as another user I get '1' and it is consistently:

ismene2 AT loreley /tmp/perl/perl-5.8.1
$ id
uid=1008(ismene2) gid=513(Domänen-Benutzer) groups=513(Domänen-Benutzer),545(Benutzer),10513(Domänen-Benutzer)

$ ls -al .patch
-rwx------    1 #gerrit  Domänen-Admins        6 Aug 15 18:51 .patch

$ [ -x .patch ]; echo $?
1

$ /usr/bin/test -x .patch; echo $?
1

$ perl -e 'print -x ".patch" ? 0 : 1 , "\n"'
1

If I try to execute as the other user I get:
$ ./.patch
-bash: ./.patch: Permission denied

$ getfacl .patch
# file: .patch
# owner: #gerrit
# group: Domänen-Admins
user::rwx
group::---
mask:rwx
other:---
