LSLOGINS(1)                      User Commands                     LSLOGINS(1)

       lslogins - display information about known users in the system

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

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

       The optional argument username forces lslogins to print all available
       details about the specified user only. In this case the output format
       is different than in case of -l or -g and unknown is username reported
       as an error.

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

       Mandatory arguments to long options are mandatory for short options

       -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.  The
              unknown group names are ignored.

              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.

              names or user IDS).  More than one login may be specified; the
              list has to be comma-separated.  The unknown login names are

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

              Don't truncate output.

       -o, --output list
              Specify which output columns to print.  The default list of
              columns may be extended if list is specified in the format

              Output all available columns.  --help to get a list of all
              supported columns.

       --time-format type
              Display dates in short, full or iso format.  The default is

              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
