One silly chmod question

[ESGLinux]

Hi all for your answers,

I´m going to tell you why I´m trying to do that. it´s more complicated that
the use of chmod,  but it is the begining ot the problem,

I have a webserver with the user apache being the owner of all under
/opt/www/.

Well, this user hasn´t a shell (it´s is /sbin/nologin) so I can´t connect
with this user.
So I use another user that makes the upgrades of my application and web
pages, (I use rsync to make this upgrades). The problem is that with this
user I can´t change the permission to the files.

One more thing, when I update one file, it changes the owner and group of
the file to the user that I use to connect.

I use this:
rsync -azv -e 'ssh ' --delete /locatpatch/* user2 at server:/opt/www/

perhaps it´s a problem with what I want to do (I know, that I can dive shell
access to the apache user and do all with it, but I prefer not to grant that
permissions to this user)

any idea?
