NAME

       ckuid, erruid, helpuid, valuid - prompts for and validates a user ID

SYNOPSIS

       ckuid [-Q] [-W width] [-m] [-d default] [-h help]
	    [-e error] [-p prompt] [-k pid [-s signal]]

       /usr/sadm/bin/erruid [-W width] [-e error]

       /usr/sadm/bin/helpuid [-W width] [-m] [-h help]

       /usr/sadm/bin/valuid input

DESCRIPTION

       The  ckuid  utility prompts a user and validates the response. It defines, among other things, a prompt message whose response should be an
       existing user ID, text for help and error messages, and a default value (which are returned if the user responds with a RETURN).

       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 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.

       Three visual tool modules are linked to the ckuid command. They are erruid (which formats and displays an error	message),  helpuid  (which
       formats	and  displays  a  help	message),  and	valuid (which validates a response). These modules should be used in conjunction with  FML
       objects. In this instance, the  FML object defines the prompt.

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 messages as help.

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

       -m	     Displays a list of all logins when help is requested or when the user makes an error.

       -p prompt     Defines the prompt message as prompt.

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

       -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 /etc/passwd.

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    Usage error.

       3    User termination (quit).
