NAME
ckpath, errpath, helppath, valpath - display a prompt; ver-
ify 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 signal]]
/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 nei-
ther -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 begin-
ning 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 EXAMPLES) is displayed.
Three visual tool modules are linked to the ckpath command.
They are errpath (which formats and displays an error mes-
sage on the standard output), helppath (which formats and
displays a help message on the standard output), and valpath
(which validates a response). These modules should be used
in conjunction with Framed Access Command Environment (FACE)
objects. In this instance, the FACE object defines the
prompt.

User Commands ckpath(1)
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 criteria.
-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.

User Commands ckpath(1)
-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 sig-
nal 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 formatted 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
