a short, usually less than 16 character "handle" of the

posix_getgrgid() to resolve the group
name and a list of its members.
GECOS is an obsolete term that refers to the finger
information field on a Honeywell batch processing system.
The field, however, lives on, and its contents have been

list containing the user's full name, office phone, office
number, and home phone number. On most systems, only the
user's full name is available.
This element contains the absolute path to the
home directory of the user.
The shell element contains the absolute path to the
executable of the user's default shell.
