NAME
       ckpath,	errpath,  helppath,  valpath  -	 display  a prompt; verify and
       return a pathname

SYNOPSIS
       ckpath [-Q] [-W width] [-a | l]	[-b | c | f  |	y]   [-n  [o  |	 z]  ]
       [-rtwx] [-d default] [-h help] [-e error] [-p prompt] [ -k pid [-s sig‐
       nal]]

       /usr/sadm/bin/errpath [-W width] [-a | l]  [-b | c | f | y]  [-n	 [o  |
       z] ]  [-rtwx] [-e error]

       /usr/sadm/bin/helppath  [-W width] [-a | l]  [-b | c | f | y]  [-n [o |
       z] ]  [-rtwx] [-h help]

       /usr/sadm/bin/valpath [-a | l]  [-b | c |  f  |	y]   [-n  [o  |	 z]  ]
       [-rtwx] input

DESCRIPTION
       The  ckpath  utility  prompts  a	 user  and  validates the response. It
       defines, among other things, a prompt message whose response should  be
       a  pathname,  text  for	help  and  error messages, and a default value
       (which is returned if the user responds with a <RETURN>).

       The pathname must obey the criteria specified by	 the  first  group  of
       options.	 If  no criteria is defined, the pathname must be for a normal
       file that does not yet exist. If neither -a (absolute) or -l (relative)
       is given, then either is assumed to be valid.

       All  messages  are limited in length to 79 characters and are formatted
       automatically. Tabs and newlines are removed after a single white space
       character  in  a message definition, but spaces are not removed. 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  mes‐
       sage (as defined under EXAMPLES) is displayed.

       Three  visual  tool  modules are linked to the ckpath command. They are
       errpath (which formats and displays an error message  on	 the  standard
       output),	 helppath  (which  formats  and displays a help message on the
       standard output), and valpath (which validates a response). These  mod‐
       ules  should be used in conjunction with Framed Access Command Environ‐
       ment (FACE) objects. In this instance,  the  FACE  object  defines  the
       prompt.

OPTIONS
       The following options are supported:

       -a	       Pathname must be an absolute path.

       -b	       Pathname must be a block special file.

       -c	       Pathname must be a character special file.

       -d default      Defines	the  default  value as default. The default is
		       not validated and so does not have to meet  any	crite‐
		       ria.

       -e error	       Defines the error message as  error.

       -f	       Pathname must be a regular file.

       -h help	       Defines the help message as  help.

       -k pid	       Specifies that process ID pid is to be sent a signal if
		       the user chooses to quit.

       -l	       Pathname must be a relative path.

       -n	       Pathname must not exist (must be new).

       -o	       Pathname must exist (must be old).

       -p prompt       Defines the prompt message as prompt.

       -Q	       Specifies that quit is not allowed as a valid response.

       -r	       Pathname must be readable.

       -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.

       -t	       Pathname must be creatable (touchable).	Pathname  will
		       be created if it does not already exist.

       -w	       Pathname must be writable.

       -W width	       Specify that prompt, help and error messages be format‐
		       ted to a line length of width.

       -x	       Pathname must be executable.

       -y	       Pathname must be a directory.

       -z	       Pathname must have a file having a  size	 greater  than
		       zero bytes.

OPERANDS
       The following operand is supported:

       input	       Input to be verified against validation options.

EXAMPLES
       The  text of the default messages for ckpath depends upon  the criteria
       options that have been used.

       Example 1: Default prompt

       An example default prompt for ckpath (using the -a option) is:

       example% ckpath -a
       Enter an absolute pathname [?,q]

       Example 2: Default error message

       An example default error message (using the -a option) is:

       example% /usr/sadm/bin/errpath -a
       ERROR: A pathname is a filename, optionally preceded by parent directories.
       The pathname you enter: - must begin with a slash (/)

       Example 3: Default help message

       An example default help message (using the -a option) is:

       example% /usr/sadm/bin/helppath -a
       A pathname is a filename, optionally preceded by parent directories.
       The pathname you enter: - must begin with a slash (/)

       Example 4: The quit option

       When the quit option is chosen (and allowed), q is returned along  with
       the return code 3. Quit input gets a trailing newline.

       Example 5: Using the valpath module

       The  valpath  module will produce a usage message on stderr. It returns
       0 for success and non-zero for failure.

       example% /usr/sadm/bin/valpath
       usage: valpath [-[a|l][b|c|f|y][n|[o|z]]rtwx] input
	   .
	   .
	   .

EXIT STATUS
       The following exit values are returned:

       0	Successful execution.

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

       2	Mutually exclusive options.

       3	User termination (quit).

       4	Mutually exclusive options.
