User Commands ckkeywd(1)
NAME
ckkeywd - prompts for and validates a keyword
SYNOPSIS
ckkeywd [-Q] [-W width] [-d default] [-h help] [-e error]
[-p prompt] [ -k pid [-s signal]] keyword [...]
DESCRIPTION
ckkeywd prompts a user and validates the response. It
defines, among other things, a prompt message whose response
should be one of a list of keywords, text for help and
error messages, and a default value (which will be returned
if the user responds with a carriage return). The answer
returned from this command must match one of the defined
list of keywords.
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.
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 criteria.
-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.
-p prompt Defines the prompt message as prompt.
