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.

       --notruncate
              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 -afL).

       -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 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.

NOTES

       The default UID thresholds are read from /etc/login.defs.

EXIT STATUS

       0      if OK,

       1      if incorrect arguments specified,

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