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).
