NAME
       ckuid, erruid, helpuid, valuid - prompt for and validate 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] [-e error]
       /usr/sadm/bin/helpuid [-W] [-m] [-h help]
       /usr/sadm/bin/valuid input

DESCRIPTION
       ckuid 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
       will be returned if the user responds with a carriage return).

       All messages are limited in length to 70 characters and are formatted
       automatically.  Any white space used in the definition (including
       newline) 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 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 NOTES) will be 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.

       The options and arguments for this command are:

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

       -W     Specifies that prompt, help and error messages will be
              formatted to a line length of width.

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

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

       -h     Defines the help messages as help.

       -e     Defines the error message as error.

       -p     Defines the prompt message as prompt.

       -k     Specifies that process ID pid is to be sent a signal if the

              user chooses to abort.

       -s     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.

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.
         Select the help option (?) for a list of valid login names.
         (Last line appears only if the -m option of ckuid is used)

       The default help message is:

         Please enter the login name of an existing user.
         (If the -m option of ckuid is used, a list of valid groups is also
         displayed.)

       When the quit option is chosen (and allowed), q is returned along
       with the return code 3.  The valuid module will not produce any
       output.  It returns zero for success and non-zero for failure.
