And what heuristic would you apply to identify that the script was executable.
We try to be accomodating in cygwin, so we look for things like '#!' and ':'
at the beginning of a file to verify that a script is executable but
trying to parse the above is not something that I think makes sense.
You can, of course, use ntsec on Windows NT, if you want to have true
UNIX permissions. That really is the best, and fastest way to get what
you want.
If you don't have NT, or are on a FAT partition, then
(drum roll, please)
