logins(1M) System Administration Commands logins(1M)NAMElogins - list user and system login information
SYNOPSIS
/usr/bin/logins [-admopstux] [-g group...]
[-l login_name...]
DESCRIPTION
This command displays information on user and system logins known to
the system. Contents of the output is controlled by the command options
and can include the following: user or system login, user id number,
passwd account field value (user name or other information), primary
group name, primary group id, multiple group names, multiple group ids,
home directory, login shell, and four password aging parameters. The
default information is the following: login id, user id, primary group
name, primary group id and the account field value. Output is sorted by
user id, system logins, followed by user logins.
OPTIONS
Options may be used together. If so, any login that matches any crite‐
ria are displayed.
The following options are supported:
-a Add two password expiration fields to the display.
The fields show how many days a password can remain
unused before it automatically becomes inactive,
and the date that the password expires.
-d Selects logins with duplicate uids.
-g group Selects all users belonging to group, sorted by
login. Multiple groups can be specified as a comma-
separated list. When the -l and -g options are com‐
bined, a user is only listed once, even if the user
belongs to more than one of the selected groups.
-l login_name... Selects the requested login. Multiple logins can be
specified as a comma-separated list. Depending on
the nameservice lookup types set in /etc/nss‐
witch.conf, the information can come from the
/etc/passwd and /etc/shadow files and other name‐
services. When the -l and -g options are combined,
a user is only listed once, even if the user
belongs to more than one of the selected groups.
-m Displays multiple group membership information.
-o Formats output into one line of colon-separated
fields.
-p Selects logins with no passwords.
-s Selects all system logins.
-t Sorts output by login instead of by uid.
-u Selects all user logins.
-x Prints an extended set of information about each
selected user. The extended information includes
home directory, login shell and password aging
information, each displayed on a separate line. The
password information currently consists of password
status:
NP Account has no password
LK Account is locked for UNIX authentication
NL Account is a no login account
PS Account probably has a valid password
UN Account password status is unknown. That is,
it is not a recognizable hashed password or
any of the above entries. See crypt(3C) for
valid password hashes.
If the login is passworded, status is followed by
the date the password was last changed, the number
of days required between changes, and the number of
days allowed before a change is required. The pass‐
word aging information shows the time interval that
the user receives a password expiration warning
message (when logging on) before the password
expires.
