ckkeywd - prompts for and validates a keyword


ckkeywd [-Q] [-W width] [-d default] [-h help] [-e error]
[-p prompt] [-k pid [-s signal]] keyword [...]


ckkeywd prompts a user and validates the response. It defines, among

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

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.


The following options are supported:

-d default

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

Specifies that quit will not be allowed as a valid

-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

formatted to a line length of width.


The following operand is supported:

Defines the keyword, or list of keywords, against which the
answer will be verified.


The following exit values are returned:

EOF on input, or negative width on -W option, or no keywords from
which to choose, or usage error.
