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−expirationDisplay data about the date of last password change and the account expiration date (see shadow(5) for more info). (Requires root privileges.)
−−btmp−file
pathAlternate 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.
−f, −−failedDisplay data about the users' last failed login attempts.
−G, −−supp−groupsShow information about groups.
−g, −−groups=groupsOnly show data of users belonging to groups. More than one
group may be specified; the list has to be
comma-separated.
−h, −−helpDisplay help information and exit.
−L, −−lastDisplay data containing information about the users' last login sessions.
−l, −−logins=loginsOnly 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, −−newlineDisplay each piece of information on a separate line.
−−noheadingsDo not print a header line.
−−notruncateDon't truncate output.
−o, −−output listSpecify which output columns to print. Use
−−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−accs[=threshold]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). The UID threshold can also be specified explicitly (necessary for some distributions that allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).
−−time−format
typeDisplay 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[=threshold]Show user accounts. These are by default all accounts with UID above 1000 (inclusive), with the exception of either nobody or nfsnobody (UID 65534). The UID threshold can also be specified explicitly (necessary for some distributions that allocate UIDs starting from 100, 500 - or an entirely different value - rather than 1000).
−V, −−versionDisplay version information and exit.
−−wtmp−file
pathAlternate path for wtmp.
−Z, −−contextDisplay the users' security context.
−z, −−print0Delimit user entries with a nul character, instead of a newline.
0if OK,
1if incorrect arguments specified,
2if a serious error occurs (e.g. a corrupt log).
The lslogins
utility is inspired by the logins utility, which first
appeared in FreeBSD 4.10.
The lslogins command is part of the util-linux package and is available from Linux Kernel Archive
