uadmin

uadmin(1M)																uadmin(1M)

NAME

       uadmin - administrative control

SYNOPSIS

       /usr/sbin/uadmin cmd fcn [mdep]

       /sbin/uadmin cmd fcn [mdep]

       The uadmin command provides control for basic administrative functions. This command is tightly coupled to the system administration proce-
       dures and is not intended for general use. It may be invoked only by the super-user.

       Both the cmd (command) and fcn (function) arguments are converted to integers and passed to the	uadmin	system	call.  The  optional  mdep
       (machine  dependent) argument is only available for the cmd values of 1 (A_REBOOT), 2 (A_SHUTDOWN), or 5 (A_DUMP). For any other cmd value,
       no mdep command-line argument is allowed.

       When passing an mdep value that contains whitespaces, the string must be grouped together as a single argument enclosed within quotes,  for
       example:

       uadmin 1 1 "-s kernel/unix"

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

       uadmin(2), attributes(5)

       On  systems, shutting down the system by means of uadmin does not update the boot archive. Avoid using this command after manual editing of
       files such as /etc/system or driver.conf(4).
