That's correct, and also:

 * "id USERNAME" (passing an argument) will tell you what that user's
   group memberships will be when they login.

 * "id" (no argument) tells you what your group memberships are *now*
   in your current shell.

This may be easier than scanning the entire output of cat /etc/group,
or typing out a grep command.  It becomes even more useful if your
system is using something other than /etc/group to define group
memberships (NIS, NIS+, LDAP, etc.).
