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 combined, 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/nsswitch.conf, the information can come from the
/etc/passwd and /etc/shadow files and other nameservices. 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 pass‐
word 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
UP
This account has not yet been activated by the administrator
and cannot be used.
PS
Account probably has a valid password
UN
Account password status is unknown. That is, it is not a recog‐
nizable 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 password aging information shows the time interval
that the user receives a password expiration warning message (when
logging on) before the password expires.
