NAME
       logins - Lists user account information

SYNOPSIS
       logins [-adDmopstux] [-z string] [-g groups] [-l logins]

OPTIONS
       Displays	 two  additional  fields  indicating  password expiration. The
       first shows the number of days remaining before the  password  expires.
       The  second shows the date when the password expires.  Causes logins to
       list system-specific default attributes. You must be root to run logins
       with  this  option.  This  option causes logins to list system-specific
       default attributes.  Displays only those logins who have duplicate user
       IDs.   Displays	logins	of all users belonging to the specified group.
       You can specify multiple groups as a  comma  separated  list.  If  this
       option  is  used with the -l option, the user only will be listed once,
       even if the user belongs to more than one group.	 Displays an  individ‐
       ual  login  or  a group of logins, which are specified as a comma sepa‐
       rated list.  Reports an additional line of group information  for  each
       group  the  login  belongs  to.	 Reports the output in colon separated
       fields.	Displays only the logins that do not have passwords.  Displays
       logins  whose user ID is less than 100; these are system logins.	 Sorts
       the output by login name. The default is to sort by user ID.   Displays
       logins  whose  user  ID is greater than or equal to 100; these are user
       logins.	Extends the information for each user by displaying on	subse‐
       quent  lines the user's home directory, the user's login shell, and the
       password information. The password information consists of two  charac‐
       ters  indicating	 the  password	status (PS means password, NP means no
       password or LK for locked) followed by four fields indicating  password
       aging  information.  This  information shows the last date the password
       was changed, the number of days when a password remains in effect,  the
       number  of  days required until the password must be changed again, and
       the number of days before the password expires when the	user  will  be
       given  a	 password  expiration  warning	message	 on logging in.	 Where
       string can be either distributed=n  or local=n.

	      If string is distributed=n (where the value of n can be either 0
	      or  1), this option indicates that the group is distributed.  If
	      n is 1, the login is maintained across an NIS cell. If n	is  0,
	      the login is maintained on the local system only.

	      If  string  is  local=n (where the value of n can be either 0 or
	      1), this option indicates that the login is local.  If n	is  1,
	      the  login  exists  in  a	 local	database. If n is 0, the login
	      information does not exist in a local database,  but  may	 exist
	      within the NIS cell.

	      The  following  table explains the valid combinations for the -z
	      distributed and -z local flags:

	      NIS	   local=   distributed=   Result
	      non-NIS	   0	    0		   Illegal option
	      0		   1	    Illegal
				    option
	      1		   0	    Local  Data‐
				    base
	      1		   1	    Illegal
				    option
	      NIS client   0	    0		   Illegal option
	      0		   1	    Distributed
				    Database

	      1		   0	    Local  Data‐
				    base
	      1		   1	    Both   Data‐
				    bases
	      NIS master   0	    0		   Illegal option
	      0		   1	    Distributed
				    Database
	      1		   0	    Local  Data‐
				    base
	      1		   1	    Both   Data‐
				    bases

	      The combination of -z distributed=1 and -z local=1 reports login
	      information for both local and distributed NIS databases.

DESCRIPTION
       The logins command displays a list of user accounts and information  on
       the specified user account or accounts.

       Without arguments, logins lists all the users, one on each line.

       On a non-NIS system, logins displays only the local accounts. On a NIS-
       CLIENT or NIS-MASTER system. If a user is on an NIS-CLIENT or  NIS-MAS‐
       TER  database,  the  loginscommand displays both the local and the dis‐
       tributed accounts.

       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.

EXAMPLES
       The  following  example	shows how to display the login information for
       all users.  $ logins

       The  following  example shows how to display extended login information
       about the user with the login name john.	 $ logins  -x -l john The fol‐
       lowing  example	shows  how to display all users who have multiple User
       IDs.  $ logins -d

       The following example shows how to display the user  defaults  for  the
       system.	$ logins -D

	      You  must	 be  root  to  use this option.	 The following example
	      shows how to display the login information for  all  users  with
	      system  user  accounts  (that  is,  User	IDs less than 100).  $
	      logins -s

	      The following example shows how to display  information  on  the
	      network  user  with  the	login name john.  $ logins -z distrib‐
	      uted=1 -l john
