Synopsis

logins [-dmopstuxab] [-g groups] [-l logins]

Description

logins displays information on user and system logins. Contents of the output is controlled by the command options and can include the following: user or system login, user ID number, /etc/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 from /etc/passwd. Output is sorted by user id, displaying system logins followed by user logins.

-d: Selects logins with duplicate uids.
-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 consists of password status (PS for passworded, NP for no password or LK for locked), the date the password was last changed, the number of days required between changes, the number of days allowed before a change is required, and the number of days that the user will receive a password expiration warning message (when logging on) before the password expires.
-a: Adds 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 will expire.
-b: Print's the user's audit event mask. This option is valid only if the Auditing Utilities are installed.
-g: Selects all users belonging to group, sorted by user id. Multiple groups can be specified as a comma-separated list.
-l: Selects the requested login. Multiple logins can be specified as a comma-separated list.

Notices

When options are combined, any login matching any criteria will be displayed. When the -l and -g options are combined, users will only be listed once, even if they belong to more than one of the selected groups.
