LSLOGINS(1)                      User Commands                     LSLOGINS(1)

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

              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.

              Don't truncate output.

       -o, --output list
              Specify which output columns to print.  Use --help to get a list
              of all supported columns.

       -p, --pwd
              Display information related  to  login  by  password  (see  also

              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
              nfsnobody (UID 65534).  This hardcoded default maybe overwritten
              by parameters UID_MIN and UID_MAX in the file /etc/login.defs.

       -V, --version
              Display version information and exit.

       --wtmp-file path
              Alternate path for wtmp.

       -Z, --context
              Display the users' security context.

       -z, --print0
              Delimit user entries with a nul character, instead of a newline.

       1      if incorrect arguments specified,

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