LSLOGINS(1)

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.

Mandatory arguments to long options are mandatory for short options too.

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

OPTIONS

Display info about existing users.

-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 priviliges.)

-e, --export
    Output data in the format of NAME=VALUE.

-f, --failed
    Display data about the users' last failed login attempts.

-G, --groups-info
    Show information about 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.

-l, --logins=LOGINS
    Only show data of users with a login specified in LOGINS. More than one login may be specified; the list has to be comma-separated.

-L, --last
    Display data containing information about the users' last login sessions.

-m, --supp-groups
    Show supplementary groups.

--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 -afR).

-r, --raw
    Raw output (no columnation).

-s, --system-accs
    Show system accounts. These are by the default all accounts with UID below 1000 (non-inclusive), with the exception of either nobody or nfsnobody (UID 65534). The UID treshold can also be specified explicitly (necessary for some distributions that allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).

--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 the default all accounts with UID above 1000 (inclusive), with the exception of either nobody or nfsnobody (UID 65534). The UID treshold can also be specified explicitly (necessary for some distributions that allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).

-Z, --context
    Display the users' security context.

--wtmp-file path
    Alternate path for wtmp.

--btmp-file path
    Alternate path for btmp.

-h, --help
    Display help information and exit.

-V, --version
    Display version information and exit.

NOTES
The default UID tresholds 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).
