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
/etc/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. The 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. The unknown login names are ignored.
- -n, --newline
- Display each piece of information on a separate line.
- --noheadings
- Do not print a header line.

- -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

This hardcoded default maybe overwritten by parameters UID_MIN and UID_MAX

The lslogins utility is inspired by the logins
utility, which first appeared in FreeBSD 4.10.
