NAME
lslogins - display information about known users in the systemSYNOPSIS
lslogins [options] [-s|-u[=UID]] [-g groups] [ -l logins] [username]DESCRIPTION
Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /passwd and output the desired data.OPTIONS
Mandatory arguments to long options are mandatory for short options too.Display data about the date of last password
change and the account expiration date (see shadow(5) for more info).
(Requires root privileges.)
Alternate path for btmp.
Separate info about each user with a colon
instead of a newline.
Output data in the format of NAME=VALUE. See
also option --shell.
Display data about the users' last failed
login attempts.
Show information about supplementary
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 the relation between user and group may be invisible for the primary
group if the user is not explicitly specified as group member (e.g., in
/etc/group). If the command lslogins scans for groups then it
uses the groups database only, and the user database with primary GID is not
used at all.
Display data containing information about the
users' last login sessions.
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.
Display each piece of information on a
separate line.
Do not print a header line.
Don’t truncate output.
Specify which output columns to print. The
default list of columns may be extended if list is specified in the
format +list.
Output all available columns. --help to
get a list of all supported columns.
Display information related to login by
password (see also -afL).
Raw output (no columnation).
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.
Display dates in short, full or iso format.
The default is short, this time format is designed to be space efficient and
human readable.
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.
Display help text and exit.
Print version and exit.
Alternate path for wtmp.
Alternate path for lastlog(8).
The column name will be modified to contain
only characters allowed for shell variable identifiers. This is usable, for
example, with --export. Note that this feature has been automatically
enabled for --export in version 2.37, but due to compatibility issues,
now it’s necessary to request this behavior by --shell.
Display the users' security context.
Delimit user entries with a nul character,
instead of a newline.
EXIT STATUS
0if OK,
if incorrect arguments specified,
if a serious error occurs (e.g., a corrupt
log).
NOTES
The default UID thresholds are read from /etc/login.defs.HISTORY
