    The following form allows you to view linux man pages.

    Command:

    upsrw

    
    
    

    SYNOPSIS

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

    DESCRIPTION

           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 you.
    
    
    

    OPTIONS

           -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 input.transfer.high=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 NUT 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 command line. NUT usernames
               are defined in upsd.users(5), and are not linked to system
               usernames.
    
           -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 upsname[@hostname[:port]]. The default hostname is "localhost".

    HISTORY

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