chmod help
 

I have a large directory with about 60GB worth of subdirectories and files beneath it. I would like only root to have access to delete anything in that directory, while any user can read the files (say mp3's and I want any user to be able to play them). I keep thinking would give me read access to the files as a regular user, but it does not.

Since the directory in question is a subdirectory, do I need to give the same permissions all the way up the tree? is that where I'm making my mistake?

Hi,

your mistake is that a directory must be executable in order to access it. You'll have to give 644 to all files but 755 to all directories.

If you want to traverse subdirectories you need something like Capital "X" means: permision "x" only for directories.

Hi

-rw-r--r--
user.group.all

First you need to changed the owner to root

chown -R root.root /foo/bar

then remove write access of other user

chmod -R 745 /foo/bar
7 means only root can read write or execute
4 groups can only read
5 all user can read and execute

I hope that will help
