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?

enter image description here

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.

enter image description here

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

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.

Actually, o means "other users." a is short for ugo. uga+rw is equivalent to ugo+rw, but they're only equivalent when u and g are specified. – Eliah Kagan Jul 14 '12 at 14:59
actually "a" means "all" (which should be the default). the letter "o" is for "other". unless your referring to using the "o" in addition to another permission and not trying to define the ownership. – nicholas shake Jan 2 at 6:36

try by using numeric values

chmod -R 660 directorymainname

That will remove the execute bit from all directories in the specified tree, for all users, which will prevent anybody from entering the directories. – Eliah Kagan Jul 14 '12 at 14:58
