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  mes‐
       sage (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	crite‐
		       ria.

       -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).

NOTES
       The default prompt for ckuid is:

       Enter the login name of an existing user [?,q]:

       The default error message is:

       ERROR - Please enter the login name of an existing user.

       returns	0 for success and non-zero for failure.
