LSLOGINS(1)

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, --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).
