What makes it good to ask permission?
Asking permission builds safety by showing respect. People naturally place a high value on their autonomy. When we attempt force them into a conversation, they often resist our attempts even though the content of the conversation we want to have may be in their best interest.
How do I give permission to user?
To change directory permissions for everyone, use “u” for users, “g” for group, “o” for others, and “ugo” or “a” (for all). chmod ugo+rwx foldername to give read, write, and execute to everyone. chmod a=r foldername to give only read permission for everyone.
