How can I change permissions of a folder, including its enclosed files and subdirectories?

I need to recursively change the permissions of all folders, sub-folders and files from within ~/.local/share/Trash/expunged Does anyone have a clue or idea on how to do this?

I have tried following the instructions from this question but to no avail. chmod -R ug+rw <foldername> doesn't seem to be working for this folder, its subdirectories, or enclosed files.

Does anyone know the chmod command to change these permissions? For example:

root@santos:/home/santos/.local/share/Trash# ls -l
total 12
drwx------ 3 santos santos 4096 Mar 21 21:38 expunged
drwx------ 2 santos santos 4096 Mar 21 21:38 files
drwx------ 2 santos santos 4096 Mar 21 21:38 info

Solution 1:

From the screenshot it seems like the chmod command worked well. As you wrote chmod -R ug+rw it gave a read/write permission to the user and group of the recursive folders.

If you want to give everybody a read/write permission you should add 'a' to your command so that it will be chmod -R uga+rw.

Solution 2:

try by using numeric values

chmod -R 660 directorymainname
