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]]
errgid [-W width] [-e error]
helpgid [-W width] [-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 is 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
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
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 NOTICES) is 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 Do not allow quit as a valid response.
-W Use width as the line length for prompt, help, and error
messages.
-m Display a list of all groups when help is requested or
when the user makes an error.

-d The default value is default. The default is not
validated and so does not have to meet any criteria.
-h The help message is help.
-e The error message is error.
-p The prompt message is prompt.
-k Send process ID pid a signal if the user chooses to
abort.
-s When quit is chosen, send signal to the process whose
pid is specified by the -k option. If no signal is
specified, use SIGTERM.
