ckdate(1)                        User Commands                       ckdate(1)

       ckdate, errdate, helpdate, valdate - prompts for and validates a date

       ckdate  [-Q]  [-W width]  [-f format] [-d default] [-h help] [-e error]
       [-p prompt] [ -k pid [-s signal]]

       /usr/sadm/bin/errdate [-W width] [-e error] [-f format]

       /usr/sadm/bin/helpdate [-W width] [-h help] [-f format]

       /usr/sadm/bin/valdate [-f format] input

       The ckdate utility prompts  a  user  and  validates  the  response.  It
       defines,  among other things, a prompt message whose response should be
       a date, text for help and error messages, and a  default  value  (which
       will  be  returned  if  the  user  responds with a  <&lt;RETURN>&gt;). The user
       response must match the defined format for a date.

       All messages are limited in length to 70 characters and  are  formatted
       automatically.  Any  white space used in the definition (including new-
       line) 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 mes-
       sage (as defined under NOTES) will be displayed.

       Three visual tool modules are linked to the ckdate  command.  They  are
       errdate  (which formats and displays an error message), helpdate (which
       formats and displays a help message), and valdate  (which  validates  a
       response).  These  modules  should  be  used  in  conjunction  with FML
       objects. In this instance, the FML object defines the prompt. When for-
       mat  is  defined in the errdate and helpdate modules, the messages will
       describe the expected format.

       The following options are supported:

       -d default      Defines the default value as default.  The default does
                       not have to meet the format criteria.

       -e error        Defines the error message as error.

       -f format       Specifies  the  format  against which the input will be
                       verified. Possible formats and their definitions are:

                       %b  =    abbreviated month name (jan, feb, mar)

                       %B  =    full month name %d  = day of month (01 - 31)

                       %D  =    date as %m/%d/%y (the default format)

                       %e  =    day of month (1 - 31; single digits  are  pre-
                                ceded by a blank)

                       %h  =    abbreviated month name, identical to %b%

                       %m  =    month number (01 - 12)

                       %y  =    year within century (for instance, 89)

                       %Y  =    year as CCYY (for instance, 1989)

       -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

       -s signal       Specifies  that  the process ID pid defined with the -k
                       option  is to be sent signal signal when quit  is  cho-
                       sen.  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.

       The following operand is supported:

       input           Input to be verified against format criteria.

       The following exit values are returned:

       0        Successful execution.

       1        EOF on input, or negative width on  -W option, or usage error.

       3        User termination (quit).

       4        Garbled format argument.

       The default prompt for ckdate is:

       Enter the date [?,q]:

       The default error message is:

       ERROR - Please enter a date.  Format is <format>.

       The default help message is:

       Please enter a date. Format is <format>.

       When  the quit option is chosen (and allowed), q is returned along with
       the return code 3. The valdate module will not produce any output.   It
       returns zero for success and non-zero for failure.
