The group is www(basic apache user/group) which doesnot have any home directory.
The users in that group should be able to change the file permissions of the files owned by that group www.

i.e users shd be able to chmod the files having ownership www.www

Please stop this barrage of homework questions immediately.

To copy the files and directories keeping the permissions you can use --preserve option with cp command.

Since you appeared to ignore my request to stop this, I have given you a "time out". LQ is not a place where you can simply drop off your assignment sheets from school. If you have any questions, please contact me or any moderator.

Hi
If you know the IP use ping 192.xx.x.x
Solutions for all the questions in the threads you posted now are available in any Linux Beginners book. Please refer them.

This is the case with apache user www(which is non-existant and has no home directory)
Users in that group www should be able to change permissions(chmod) of the files owned by group www(i.e files having ownership permissions www.www)

Why is this in the server section?

As such, all of these homework questions have been merged into one thread, and the thread closed.
From now on, please adhere to the LQ Rules, and take Pixellanys advice on how to reasonably ask for help with homework-type questions.

Thread closed.
