Question

How to block the renaming of a Particular Folder by Ubuntu Users ?

Answer 1

You have to set the ownership and permissions of the parent directory (in particular the write flag) only to the user/group which shall be able to change it.

Renaming in the end means writing to the folder which contains the file/folder.

Step 1 - ownership

sudo chown <USERNAME>:<GROUPNAME> </path/to/parent_folder>

• This makes the file or folder be owned by the user <USER> (for blocking all normal users from the change this could be e.g. root).

• The :<GROUPNAME> is optional and sets the group to for that file or folder.

If you don't need a special group I'ld recommend use the 's group. If you want multible users to be able to change, add them all to a new usergroup and set the ownership e.g. to

sudo chown root:<GROUPNAME> </path/to/parent_folder>

---

To verify it is setup as it should run

ls -la </path/to/parent_folder>

• This shows you the a list of contained files and the very first entry . the folder itself with information about ownership and permissions.

Output could look like

drwxrwxr-x   1 root root     0 Dec  4 16:59 .

Step 2 - permissions

followed by

sudo chmod u+w </path/to/parent_folder>
sudo chmod g+w </path/to/parent_folder>
sudo chmod o+w </path/to/parent_folder>

This makes

• u+r the owner(user) is allowed to write
• g+r the group is allowed to write (this is optional and in some cases not wanted -> than change it to g-r)
• o-r other users are not allowed to write

---

In some cases you might also want the -R option for all commands to set the ownership and permissions recursively also on the content of a folder.

Note:
Anyway there is no way to prevent that root changes anything in your system. So other users could still change using sudo.
