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]]

errgid [-W] [-e error]
helpgid [-W] [-m] [-h help]
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 definition (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 message), 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. The options and arguments for this command are:

-Q         Specifies that quit will  not  be  allowed  as  a
           valid response.
-W width   Specifies that prompt, help  and  error  messages
           will be formatted to a line length of width.
-m         Displays a  list  of  all  groups  when  help  is
           requested or when the user makes an error.
-d default Defines  the  default  value  as  default.    The
           default  is not validated and so does not have to
           meet any criteria.
-h help    Defines the help messages as help.
-e error   Defines the error message as error.
-p prompt  Defines the prompt message as prompt.
-k pid     Specifies that process ID pid is  to  be  sent  a
           signal if the user chooses to abort.
-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.
input      Input to be verified against /etc/group

EXIT CODES

0 = Successful execution
1 = EOF on input
2 = Usage error
3 = User termination (quit)

NOTES

The default prompt for ckgid is:

     Enter the name of an existing group [?,q]:
  The default error message is:

    ERROR - Please enter the name of an existing group.
    (if the -m option of ckgid is used, a list of valid  groups
    is displayed here)
 The default help message is:

   Please enter an existing group name.
   (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 pro-
duce any output.  It returns zero for success and non-zero  for
failure.
