NAME
       ckgid, errgid, helpgid, valgid - prompt for and validate 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] [-e error]
       /usr/sadm/bin/helpgid [-W] [-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 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 produce any
       output.  It returns zero for success and non-zero for failure.
