logins -- display account information
SYNOPSIS
logins [-admopstux] [-g groups] [-l logins]

The logins utility displays information about user and system accounts.
The following options are available:
-a Display information about the password change and account expiration times for each account.
-d Select accounts with duplicate UIDs.
-g groups Select accounts that are members of the specified groups. If multiple group names are specified, they must be separated with com-

-m Show information about secondary groups.
-o Display the information for each account on a single line of colon-separated fields.

-t Sort selected accounts by name rather than by UID.
-u Select user accounts. These are currently defined as accounts with UIDs above 1000, except the ``nobody'' account (UID 65534).

LSLOGINS(1) User Commands 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.
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

-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.
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

or nfsnobody (UID 65534). This hardcoded default maybe 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 nfs-
nobody (UID 65534). This hardcoded default maybe overwritten by parameters UID_MIN and UID_MAX in the file /etc/login.defs.
