[SOLVED] Linux Server User Permissions

threegig · 12-21-2014, 01:34 AM

Hi Guys I am setting up a small Ubuntu server so I can share folders with the rest of my home network. I want users to be able to view folders and copy files but not allow users to cut or change files.
What permissions should I set. Is read the same as copy?
Thanks

Set permissions as r-x

chmod -R u=rwx,g=rx,o=rx directory

Thanks Veerain
I had a look at the chmod man page and I understand the
r - read w-write and x-execute commands but what command relates to the copying of a file. Does read allow copying?
I am just trying to understand the commands as it will help me in the future.
Thanks and have a great Xmas.

Yes read permission on a file allows copying it.

User rights/Permissions

- The first character that I marked with an underscore is the special permission flag that can vary.
- The following set of three characters (rwx) is for the owner permissions.
- The second set of three characters (rwx) is for the Group permissions.
- The third set of three characters (rwx) is for the All Users permissions.

The Permission Groups used are:

u - Owner
g - Group
o or a - All Users

The potential Assignment Operators are + (plus) and - (minus); these are used to tell the system whether to add or remove the specific permissions.

The Permission Types that are used are:

r - Read
w - Write
x - Execute
