Answer: id, /usr/bin/id

Explanation:

The id command will display the user ID (uid), the primary group ID (gid), and the supplementary groups (groups) of a user. The output will show the names and the numerical IDs of the groups.

For example:

id linuxize

The command will show the user ID (uid), the user’s primary group (gid), and the user’s secondary groups (groups)

uid=1001(linuxize) gid=1001(linuxize) groups=1001(linuxize),27(sudo) To print only the names instead of the numbers use the -n option. id -nG linuxize

The command will show only the names of the groups

linuxize sudo

The id command is part of the GNU coreutils package and is available on all Linux systems. The full path of the command is /usr/bin/id.
