chmod question

[elemental09]

Hello,

I want to give a mounted folder /mnt/folder

access so that 'root and the group test have read write access'

and all other users have read access

I understand most of the chmod command, the users groups world etc
but where in the 'command' do you specify which 'group' or 'user' you are
giving the read / write access to? in all the tutorials i've seen no where do you specify the actual group or user.

Have a look at

man chown

Agree with irithori, you have to change the ownership of that folder to root and its usergroup. chown (file/foldername) (user)

'root and the group test have read write access'

and all other users have read access

first check its owner and permission using ls -l
then sudo chown test:test -R /mnt/folder (this will change the owner and group into test)

then probably sudo chmod 766 -R /mnt/folder

where in the 'command' do you specify which 'group' or 'user' you are
giving the read / write access to?

normally owner of file have access to change its permission. CMIIW, anyone who upload or create the file will be the first owner of its file. check file owner and permission using ls -l. then change to whoever you want using root access
