Permissions to DIR

praveenv · 08-26-2004, 06:44 AM

Dear Friends !

I logged in as root and I changed one DIR permissions (no rwx to anyone including owner also here owner of DIR is "root" itself). , but I was able to see the contents of DIR and I can "cd" to it

WHY its happening like that ?

Because a execution permission on a directory means entering that directory and read permission means directory listing. For example when a directory has a permission r-- then you can `ls dir' and see the contents but cannot enter it; when a directory has the permission -w- then you can create files in the directory without entering it; and when a directory has the permission --x you can enter in but cannot create files in it or list the contents of it. You have to give at least r-x for using `cd' and `ls'.

If you're root, you have unlimited access to everything. There are no permissions/restrictions on root.

D'oh! I read the praveenv's message as "i can't" and didn't noticed the login name `root'. I'm sorry about that.
