NAME

       lslogins - display information about known users in the system

SYNOPSIS

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

DESCRIPTION

       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.

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.  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.

       -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.   The
              unknown login names are ignored.

       -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.  The default list of columns may be extended
              if list is specified in the format +list.

       --output-all
              Output all available columns.  --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 between 101 and
              999  (inclusive),  with  the  exception  of either nobody or nfsnobody (UID 65534).
              This hardcoded default may be 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, --print0
