LSLOGINS(1) User Commands LSLOGINS(1)
lslogins - display information about known users in the system
lslogins [options] [-s|-u[=UID]] [-g groups] [-l logins]
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.
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.
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.
-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. Use --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 below 1000 (non-inclusive), with the exception of either
nobody 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 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.
The default UID thresholds are read from /etc/login.defs.
0 if OK,
1 if incorrect arguments specified,
2 if a serious error occurs (e.g. a corrupt log).
group(5), passwd(5), shadow(5), utmp(5)
The lslogins utility is inspired by the logins utility, which first
appeared in FreeBSD 4.10.
