chmod for folder

hi, Experts.

I am facing a difficulty in samba sharing permission setting.. i wish to allow all permission to all nobody user, but not to allow the add and delete feature in my shared folder.

For example:

In my shared folder A, it has file A.
The user can edit and save the file A, but the user not allowed to delete the file A and also not allowed to add any files/folders in folder A.

What is the chmod command should i use to apply for folder A to meet the requirement above?

Thanks
Jack

Yes, i tried to view this before.. There is only guide for read,write and execute permission, no add or delete permission guide.

Read, write, and execute are the only priveleges you can assign. They have different meanings for files and for directories.

Have a look at the table on this page:
http://webmasterworkshop.com/guides/chmod_guide.shtml
and the Wikipedia article:
http://en.wikipedia.org/wiki/Chmod

In your case, you could use:
chmod -R a=rw dirA
chmod a-w+x dirA

The first command assigns read and write permissions for all groups for dirA and all directories and folders beneath it.
The second modifies the permissions for dirA itself by removing the write permission (so that one cannot add or remove files) and adding execute (so that one can list the directory contents).

The problem with this approach is that only the root user will be able to modify the directory tree.
Depending on how your Samba server is set up, you could perhaps use chown to set the owner/group of the directory and assign permissions differently for user/group/owner.

chmod a-w+x dirA
yes, this make the users cannot add or remove files in this dirA folder, this work great... how about i want to able edit the file? (currently the file able for read only).

You need write permissions on the files. That's what the first command I gave you does. You need to run both, in order.

i already tried, the file become read only after executed the both command that u gave.
