ckstr(1) User Commands ckstr(1)
NAME
ckstr, errstr, helpstr, valstr - display a prompt; verify and return a string answer
SYNOPSIS
ckstr [-Q] [-W width] [ [-r regexp] [...]] [-l length]
[-d default] [-h help] [-e error] [-p prompt]
[-k pid [- s signal]]
/usr/sadm/bin/errstr [-W width] [-e error] [-l length]
[ [-r regexp] [...]]
/usr/sadm/bin/helpstr [-W width] [-h help] [-l length]
[ [-r regexp] [...]]
/usr/sadm/bin/valstr [-l length] [ [-r regexp] [...]] input
DESCRIPTION
The ckstr utility prompts a user and validates the response. It defines, among other things, a prompt message whose response should be a
string, text for help and error messages, and a default value (which are returned if the user responds with a RETURN).
The answer returned from this command must match the defined regular expression and be no longer than the length specified. If no regular
expression is given, valid input must be a string with a length less than or equal to the length defined with no internal, leading or
trailing white space. If no length is defined, the length is not checked.
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 defini-
tion, 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 EXAMPLES) is displayed.
Three visual tool modules are linked to the ckstr command. They are errstr (which formats and displays an error message on the standard
output), helpstr (which formats and displays a help message on the standard output), and valstr (which validates a response).
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 criteria.
-e error Defines the error message as error.
-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 length Specifies the maximum length of the input.
-p prompt Defines the prompt message as prompt.
-Q Specifies that quit will not be allowed as a valid response.
-r regexp Specifies a regular expression, regexp, against which the input should be validated. May include white space. If multiple
expressions are defined, the answer need match only one of them.
-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:
input Input to be verified against format length and/or regular expression criteria.
EXAMPLES
Example 1 Default prompt
The default prompt for ckstr is:
example% ckstr
Enter an appropriate value [?,q]:
Example 2 Default error message
The default error message is dependent upon the type of validation involved. The user will be told either that the length or the pattern
matching failed. The default error message is:
example% /usr/sadm/bin/errstr
ERROR: Please enter a string which contains no embedded,
leading or trailing spaces or tabs.
Example 3 Default help message
The default help message is also dependent upon the type of validation involved. If a regular expression has been defined, the message is:
example% /usr/sadm/bin/helpstr -r regexp
Please enter a string which matches the following pattern:
regexp
Other messages define the length requirement and the definition of a string.
Example 4 Using 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 valstr module
The valstr module will produce a usage message on stderr. It returns 0 for success and non-zero for failure.
example% /usr/sadm/bin/valstr
usage: valstr [-l length] [[-r regexp] [...]] 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 Invalid regular expression.
3 User termination (quit).
