id: Display the current group identity as a number.
$ id -g
try on your machine
The command "id -g" is used to display the group ID (GID) of the current user.
The "id" command is generally used to display information about a user and their group. By default, it displays the user ID (UID), group ID (GID), and a list of supplementary group IDs.
In this specific case, when you run "id -g", it will only output the GID of the current user. The GID is a numeric value assigned to a group on a Unix-like operating system. By knowing the GID, you can identify which group the user belongs to.
