RedHat 9 (Linux i386) - man page for upscmd (redhat section 8)

UPSCMD(8)			     Network UPS Tools (NUT)				UPSCMD(8)

NAME
       upscmd - UPS administration program for instant commands

SYNOPSIS
       upscmd -h

       upscmd -l ups

       upscmd [-u username] [-p password] ups command

DESCRIPTION
       upscmd  allows  you  to	invoke "instant commands" in your UPS hardware.  Not all hardware
       supports this, so check the list with -l to see if anything will work on your equipment.

       On hardware that supports it, you can use this program to start and  stop  battery  tests,
       invoke a front panel test (beep!), turn the load on or off, and more.

OPTIONS
       -h     Display the help message.

       -l ups Show  the  list  of  supported instant commands on that UPS.  Some hardware may not
	      support any of them.

       -u username
	      Set the username for the connection to the server.  This is optional, and you  will
	      be prompted for this when invoking a command if -u is not used.

       -p password
	      Set the password to authenticate to the server.  This is also optional like -u, and
	      you will be prompted for it if necessary.

       ups    Connect to that UPS.  The format for this option is [upsname@]hostname[:port].

UNATTENDED MODE
       If you run this program inside a shell script or similar to invoke  a  command,	you  will
       need  to  specify all of the information on the command line.  This means using -u and -p.
       Otherwise it will put up a prompt and your program will hang.

       This is not necessary when displaying the list, as  the	username  and  password  are  not
       required for read-only mode.

DANGEROUS COMMANDS
       Some  drivers like apcsmart(8) have built-in paranoia for the dangerous commands like OFF.
       To make them actually turn off the load, you will have to send the command twice within	a
       short  window.  That is, you will have to send it once, then send it again after 3 seconds
       elapse but before 15 seconds pass.

       This paranoia is entirely defined within the driver.  upsd and upscmd have no control over
       the timing.

DIAGNOSTICS
       upscmd  won't  work  unless you provide a valid username and password.  If you get "access
       denied" errors, make sure that your upsd.users(5) has an entry for you, and that the user-
       name you are using has permissions to SET variables.

BUGS
       There is currently no way to tell the user when the driver requires confirmation to invoke
       a command such as OFF.  Similarly, there is not yet a way to tell the user  if  a  command
       succeeds or fails.
