       upsrw - UPS variable administration tool

       upsrw ups

       upsrw -h

       upsrw -s variable [-u username] [-p password] ups

       upsrw  allows  you  to view and change the read/write variables inside your UPS.  It sends
       commands via the server upsd(8) to your driver, which configures the hardware for you.

       The list of variables that allow you to change their values is based on	the  capabilities
       of  your UPS equipment.	Not all models support this feature.  Typically, cheaper hardware
       does not support any of them.  Run upsrw with a UPS identifier to see what will	work  for

       -h     Display the help message.

       -s variable
	      Specify  the variable to be changed inside the UPS.  For unattended mode such as in
	      shell scripts, use the format VAR=VALUE to specify both the variable and the value,
	      for example:

	      -s HIGHXFER=129

	      Without  this argument, upsrw will just display the list of the variables and their
	      possible values.

	      Some variables are strings, and can be set to any value within  the  length  limit.
	      Others  are  enumerated types and can only be set to one of those values.  Refer to
	      the list to know what's available in your hardware.

       -u username
	      Set the username for the connection to the server.  This is optional, and you  will
	      be  prompted  for this when using the -s option if you don't specify -u on the com-
	      mand line.

       -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    View  or	change	the  settings  on  this  UPS.	The  format  for  this	option is

       If you run this program inside a shell script or similar to set variables, you  will  need
       to  specify all of the information on the command line.	This means using -s VAR=VALUE, -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.

       upsrw  can't  set  variables on your UPS 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 username you are using has permissions to SET variables.

       This program used to be called upsct2, which was ambiguous and confusing.

       upsd(8), upscmd(8)
