Linux – chown directory for multiple users
Create a new group for users (run commands with root rights): groupadd testgroup gpasswd -a user1 testgroup gpasswd -a user2 testgroup gpasswd -a user3 testgroup … Make that group the group owner of the directory (with root rights): chown -R user1:testgroup /your/directory Make the group writeable (with root rights): chmod -R g+w /your/directory
