Hi,
Please consider the following shell session:
$ cat dummy.c
#include <stdio.h>
int main()
{
return 0;
}
$ gcc -o dummy dummy.c
$ mv dummy.exe dummy
$ ./dummy
$ echo $?
0
$ chmod a-x dummy
$ ./dummy
-bash: ./dummy: Permission denied
$ rm dummy
$ touch dummy
$ ./dummy
$ echo $?
0
So Cygwin lets the shell to execute a zero-sized file regardless of the "x" perm
(non-empty files are not executable if they do not have "x", as shown above).
I can't reproduce this on my system. Can you show the permissions and ACL of
dummy?
There's more. If I put some rubbish in a file, Cygwin still tries to execute it even if
the "x" is not there:
$ rm dummy
$ echo "1" > dummy
$ ./dummy
./dummy: line 1: 1: command not found
Again I can't reproduce this.
I reproduce the behaviour:
> echo echo foo > bar
> ls -l bar
-rw-r--r-- 1 towo None 9 5. Aug 22:18 bar
> ./bar
foo
