NAME
       lslogins - display information about known users in the system

SYNOPSIS
       lslogins [options] [-s|-u[=UID]] [-g groups] [-l logins]

DESCRIPTION
       Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /etc/passwd and output the desired data.

       The default action is to list info about all the users in the system.

OPTIONS
       Mandatory arguments to long options are mandatory for short options too.

       -a, --acc-expiration
	      Display  data  about the date of last password change and the account expiration date (see shadow(5) for more info).  (Requires root
	      privileges.)

       --btmp-file path
	      Alternate path for btmp.

       -c, --colon-separate
	      Separate info about each user with a colon instead of a newline.

       -e, --export
	      Output data in the format of NAME=VALUE.

       -f, --failed
	      Display data about the users' last failed login attempts.

       -G, --supp-groups
	      Show information about supplementary groups.

       -g, --groups=groups
	      Only show data of users belonging to groups.  More than one group may be specified; the list has to be comma-separated.

	      Note that relation between user and group may be invisible for primary group if the user is not explicitly specify as  group  member
	      (e.g. in /etc/group). If the command lslogins scans for groups than it uses groups database only, and user database with primary GID
	      is not used at all.

       -h, --help
	      Display help information and exit.

       -L, --last
	      Display data containing information about the users' last login sessions.

       -l, --logins=logins
	      Only show data of users with a login specified in logins (user names or user IDS).  More than one login may be specified;  the  list
	      has to be comma-separated.

       -n, --newline
	      Display each piece of information on a separate line.

       --noheadings
	      Do not print a header line.

       -r, --raw
	      Raw output (no columnation).

       -s, --system-accs
	      Show  system accounts.  These are by default all accounts with a UID below 1000 (non-inclusive), with the exception of either nobody
	      or nfsnobody (UID 65534).  This hardcoded  default  maybe  overwritten  by  parameters  SYS_UID_MIN  and	SYS_UID_MAX  in  the  file
	      /etc/login.defs.

       --time-format type
	      Display  dates  in  short,  full	or iso format.	The default is short, this time format is designed to be space efficient and human
	      readable.

       -u, --user-accs
	      Show user accounts.  These are by default all accounts with UID above 1000 (inclusive), with the exception of either nobody or  nfs-

       0      if OK,

       1      if incorrect arguments specified,

       2      if a serious error occurs (e.g. a corrupt log).
