LSLOGINS(1) User Commands LSLOGINS(1)
lslogins - display information about known users in the system
lslogins [options] [-s|-u[=UID]] [-g groups] [-l logins]
[username]
Examine the wtmp and btmp logs, /etc/shadow (if necessary) and
/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.
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. 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. 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.
--lastlog path
Alternate path for lastlog.
-Z, --context
Display the users' security context.
-z, --print0
Delimit user entries with a nul character, instead of a
newline.
0 if OK,
1 if incorrect arguments specified,
2 if a serious error occurs (e.g., a corrupt log).
The default UID thresholds are read from /etc/login.defs.
The lslogins utility is inspired by the logins utility, which
first appeared in FreeBSD 4.10.
