NAME

       logins - list user and system login information

SYNOPSIS

       /usr/bin/logins [-admopstux] [-g group...]
	    [-l login_name...]

DESCRIPTION

       This  command  displays	information  on  user  and  system logins known to the system. Contents of the output is controlled by the command
       options and can include the following: user or system login, user id number, 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 param-
       eters. The default information is the following: login id, user id, primary group name, primary group id and the account field value.  Out-
       put is sorted by user id, system logins, followed by user logins.

OPTIONS

       Options may be used together. If so, any login that matches any criteria are displayed.

       The following options are supported:

       -a		   Add 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 expires.

       -d		   Selects logins with duplicate uids.

       -g group 	   Selects all users belonging to group, sorted by login. Multiple groups can be specified as a comma-separated list. When
			   the	-l  and  -g  options  are  combined,  a user is only listed once, even if the user belongs to more than one of the
			   selected groups.

       -l login_name...    Selects the requested login. Multiple logins can be specified as a comma-separated list. Depending on  the  nameservice
			   lookup  types  set in /etc/nsswitch.conf, the information can come from the /etc/passwd and /etc/shadow files and other
			   nameservices. When the -l and -g options are combined, a user is only listed once, even if the  user  belongs  to  more
			   than one of the selected groups.

       -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 currently consists of
			   password status:

			   NP	 Account has no password

			   LK	 Account is locked for UNIX authentication

			   NL	 Account is a no login account

			   PS	 Account probably has a valid password

			   UN	 Account  password  status  is	unknown.  That	is,  it  is not a recognizable hashed password or any of the above
				 entries. See crypt(3C) for valid password hashes.

			   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 receives a password expiration warning  message	(when  logging	on)  before  the  password
			   expires.
