What is difference between users and groups? Users can be either people, meaning accounts tied to physical users, or accounts which exist for specific applications to use. Groups are logical expressions of organization, tying users together for a common purpose. Users within the same group can read, write, or execute files owned by the group.
What is the difference between user and group in Linux? User: the owner of the file (person who created the file). Group: the group can contain multiple users. Therefore, all users in that group will have the same permissions. It makes things easier than assign permission for every user you want.
Where are groups stored in Ubuntu? The /etc/group file stores information about each group, including the group name, group ID (GID) and secondary user membership. The /etc/gshadow file stores additional information for the group, including group administrators and the group password.
