ckkeywd(1)            UNIX System V(Essential Utilities)             ckkeywd(1)


NAME
      ckkeywd - prompt for and validate 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 is
      returned if the user responds with a 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 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 NOTES) is displayed.

      -Q        Do not allow quit as a valid response.

      -W        Use width as the line length for prompt, help, and error
                messages.

      -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.

      keyword   The keyword, or list of keywords, against which the answer is
                to be verified is keyword.
