System Administration Commands                         logins(1M)



NAME
     logins - 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,  pri-
     mary  group  id,  multiple  group names, multiple group ids,
     home directory, login shell, and four password aging parame-
     ters.  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 criteria 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  nameser-
                         vices.  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 informa-
                         tion, each displayed on a separate line.
                         The  password information currently con-
                         sists of password status:

                               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 password aging information
                         shows the time interval  that  the  user
                         receives  a  password expiration warning
                         message (when  logging  on)  before  the
                         password expires.
