     ckuid, erruid, helpuid, valuid - prompts for and validates a
     user ID

     ckuid [-Q] [-W width] [-m] [-d default] [-h help] [-e error]
     [-p prompt] [ -k pid [-s signal]]

     /usr/sadm/bin/erruid [-W width] [-e error]

     /usr/sadm/bin/helpuid [-W width] [-m] [-h help]

     /usr/sadm/bin/valuid input

     The ckuid utility prompts a user and validates the response.
     It  defines,  among  other  things,  a  prompt message whose
     response should be an existing user ID, text  for  help  and
     error  messages,  and a default value (which are returned if
     the user responds with a <RETURN>).

     All messages are limited in length to 70 characters and  are
     formatted automatically. Any white space used in the defini-
     tion (including NEWLINE) is stripped. The -W option  cancels
     the  automatic  formatting.  When  a  tilde is placed at the
     beginning or end of a message definition, the  default  text
     is inserted at that point, allowing both custom text and the
     default text to be displayed.

     If the prompt, help or error message  is  not  defined,  the
     default message (as defined under NOTES) is displayed.

     Three visual tool modules are linked to the  ckuid  command.
     They  are  erruid  (which formats and displays an error mes-
     sage), helpuid (which formats and displays a help  message),
     and  valuid  (which  validates  a  response).  These modules
     should be used in conjunction with   FML  objects.  In  this
     instance, the  FML object defines the prompt.

     The following options are supported:

     -d default      Defines the default value as  default.   The
                     default  is  not  validated  and so does not
                     have to meet any criteria.

     -e error        Defines the error message as error.

     -h help         Defines the help messages as help.

     -k pid          Specifies that process  ID pid is to be sent
                     a signal if the user chooses to abort.

     -m              Displays a list of all logins when  help  is
                     requested or when the user makes an error.

     -p prompt       Defines the prompt message as prompt.

     -Q              Specifies that quit will not be allowed as a
                     valid response.

     -s signal       Specifies that the process  ID  pid  defined
                     with the -k option is to be sent signal sig-
                     nal when quit is chosen.  If  no  signal  is
                     specified, SIGTERM is used.

     -W width        Specifies that prompt, help and  error  mes-
                     sages  will be formatted to a line length of

     The following operand is supported:

     input           Input to be verified against /etc/passwd.

     The following exit values are returned:

     0        Successful execution.

     1        EOF on input, or negative width on  -W option,   or
              usage error.

     2        Usage error.

     3        User termination (quit).

     See attributes(5) for descriptions of the  following  attri-

    |       ATTRIBUTE TYPE        |       ATTRIBUTE VALUE       |
    | Availability                | SUNWcsu                     |


     The default prompt for ckuid is:

     Enter the login name of an existing user [?,q]:

     The default error message is:

     ERROR - Please enter the login name of an existing user.

     If the -m option is used, the default error message is:

     ERROR:  Please enter one of the following login names:  <List>

     The default help message is:

     Please enter the login name of an existing user.

     If the -m option is used, the default help message is:

     Please enter one of the following login names:  <List>

     When the quit option is chosen (and allowed), q is  returned
     along  with  the  return  code 3. The valuid module will not
     produce any output.  It returns  0 for success and  non-zero
     for failure.
