LSLOGINS(1)                     User Commands                    LSLOGINS(1)

NAME         top

       lslogins - display information about known users in the system

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       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).

              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.

              Display the users' security context.
