lslogins
(1)display information about known users in the system
Options
26-a--acc-expirationDisplay data about the date of last password change and the account expiration date (see shadow(5) for more info). (Requires root privileges.)
--btmp-filepathAlternate path for btmp.
-c--colon-separateSeparate info about each user with a colon instead of a newline.
-e--exportOutput data in the format of NAME=VALUE. See also option --shell.
-f--failedDisplay data about the users' last failed login attempts.
-G--supp-groupsShow information about supplementary groups.
-g--groupsgroupsOnly 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.
-L--lastDisplay data containing information about the users' last login sessions.
-l--loginsloginsOnly 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--newlineDisplay each piece of information on a separate line.
--noheadingsDo not print a header line.
--notruncateDon’t truncate output.
-o--outputlistSpecify which output columns to print. The default list of columns may be extended if list is specified in the format +list.
--output-allOutput all available columns. --help to get a list of all supported columns.
-p--pwdDisplay information related to login by password (see also -afL).
-r--rawRaw output (no columnation).
-s--system-accsShow 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-formattypeDisplay 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-accsShow 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.
-h--helpDisplay help text and exit.
-V--versionDisplay version and exit.
--wtmp-filepathAlternate path for wtmp.
--lastlogpathAlternate path for lastlog(8).
-y--shellThe 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.
-Z--contextDisplay the users' security context.
-z--print0Delimit user entries with a nul character, instead of a newline.
DESCRIPTION
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.
EXIT STATUS
NOTES
The default UID thresholds are read from /etc/login.defs.
Password status
Multiple fields describe password status.
"Password is locked"
"Password not required (empty)"
"Login by password disabled"
