Group management

Group management

This became relevant when working with Arduino and the Arduino IDE, where the relevant user must be added to the uucp user group.

/etc/group defines the groups of the system.

Display group membership with

groups user

If no user is provided, the current user's group names are displayed.

Add users to a group with

gpasswd -a user group

If the user added to a group is already logged in, the user must then log in/out for the change to take effect.
