Hi,

Try to remember that cygwin is a unix emulation layer for windows that
tries to emulate unix in as many respects as possible. To change the ls
source to accomadate for something windows uses to hide files, sometimes
unknown from its users, would not be unix like.

But saying that if your requirement is to have such an ls facility, that
you must have, you could of course edit the source files to add your
`windows' style hiding of files. As you mentioned it is used from php so
why not check whether or not skip files in your script.

FYI the MKS toolkit is designed for windows and not a posix system, And
thus will support these windows features. In order to do this in cygwin
changes would have to be made to stat to detect these files.

The dir command is built-into windows shells. Again follows the hiding
rules.

It it really a big deal? Worth patching fileutils to make special allowance
for?

There is no unixy analogue, so Cygwin can't help here.

Personally, I don't see the point of patching fileutils to do this - but
that's just an opinion.
