NAME

     ckgid, errgid, helpgid, valgid - prompts for and validates a
     group id


SYNOPSIS

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

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

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

     /usr/sadm/bin/valgid input


DESCRIPTION

     ckgid prompts a user and validates the response. It defines,
     among  other  things, a prompt message whose response should
     be an existing  group ID, text for help and error  messages,
     and  a  default  value  (which  will be returned if the user
     responds with a carriage 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
     will  be  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) will be displayed.

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


OPTIONS

     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-
           teria.

     -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 groups 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   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.

     0     Successful execution.

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

NOTES

     The default prompt for ckgid is:

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

     The default error message is:

     ERROR: Please enter one of the following group names: [List]

     If the -m option of ckgid is used, a list of valid groups is
     displayed here.

     The default help message is:

     ERROR: Please enter one of the following group names: [List]

     If the -m option of ckgid is used, a  list of  valid  groups
     is displayed here.

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