How to grant rights to a directory to a specific group?

Question

linux

Hello. There is some additional group to which the user belongs. It is necessary to give full rights to the directory to this group.
For example , let's say I have a user user with the main group work and additional freelance. There is a /home/freelance/ directory and you need to give the freelance group full rights to the /home/freelance/ directory.
It is not clear how to do this and how to subsequently check the rights to the directory for a specific group.

Answer 1

Change Owner chown -R freelance:freelance /home/freelance
Give All Rights to chmod -R g=rwx,o= /home/freelance
