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 cri-
teria.
-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.
-Q Specifies that quit will not be allowed as a valid
response.
-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
Specifies that prompt, help and error messages will be
formatted to a line length of width.
OPERANDS
The following operand is supported:
keyword
Defines the keyword, or list of keywords, against
which the answer will be verified.
EXIT STATUS
The following exit values are returned:
0 Successful execution.
1 EOF on input, or negative width on -W option, or no
keywords from which to choose, or usage error.
3 User termination (quit).
