Users

Users

Under Unix, there are two kinds of users:

  • The administrator (root) who has all rights to the system and is responsible for the proper functioning of the system

  • others 😃

The administrator registers each new user.

Each user is referenced by a unique identifier number (UID). The match between the UID and the name of the user is stored in a specific file passwd located in the directory /etc

Users are gathered in groups. Users in the same group can have special access to files belonging to users of this group.

Each user group is referenced by a unique identifier number (GID). The correspondence between the GID and the group name is stored in a specific group file located in the /etc directory.
