NAME
logins - list user and system login information
SYNOPSIS
logins [-admopstux] [-g groups] [-l logins]
DESCRIPTION
This command displays information on user and system logins.
Contents of the output is controlled by the command options and can
include the following: user or system login, user id number,
/etc/passwd account field value (user name or other information),
primary group name, primary group id, multiple group names, multiple
group ids, home directory, login shell, and four password aging
parameters. The default information is the following: login id, user
id, primary group name, primary group id and the account field value
from /etc/passwd. Output is sorted by user id, displaying system
logins followed by user logins.
-d Selects logins with duplicate uids.
-m Displays multiple group membership information.
-o Formats output into one line of colon-separated fields.
-p Selects logins with no passwords.
-s Selects all system logins.
-t Sorts output by login instead of by uid.
-u Selects all user logins.
-x Prints an extended set of information about each selected user.
The extended information includes home directory, login shell
and password aging information, each displayed on a separate
line. The password information consists of password status (PS
for passworded, NP for no password or LK for locked). If the
login is passworded, status is followed by the date the
password was last changed, the number of days required between
changes, and the number of days allowed before a change is
required. The password aging information shows the time
interval that the user will receive a password expiration
warning message (when logging on) before the password expires.
-a Adds two password expiration fields to the display. The fields
show how many days a password can remain unused before it
automatically becomes inactive and the date that the password
will expire.

-g Selects all users belonging to group, sorted by login.
Multiple groups can be specified as a comma-separated list.
-l Selects the requested login. Multiple logins can be specified
as a comma-separated list.
NOTES
Options may be used together. If so, any login matching any criteria
will be displayed. When the -l and -g options are combined, a user
will only be listed once, even if they belong to more than one of the
selected groups.
