How do I apply user permissions to not just folders but also all files

[ozguitarplayer]

Hi,
I want to add my daughter as a user and give her full permissions to all the same folders and files that I use.
I have given her permission to folders and their sub folders however she doesn't have rwx on the individual files within the folders.
What is the command line to set this up?

Also with the command;

chown -R root:root files

what is the -R for and when do I need or not need it?

Any help appreciated

The -R means recursive, which will apply the permissions to all subfolders and files within them.

So the -R flag is what you need.

Thanks,
I did use -R however when I switch users and go into say the mp3 folder she does not have rwx on the individual files.

What you need to do is make a group. Put yourself and your daughter as members of that group, then

chown -R you:new_group mp3folder

chmod -R 775 mp3folder
