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 cri-

     -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

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

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


     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).

     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.
