    Command:

    upscmd

    
    
    

    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 this UPS. The format is upsname[@hostname[:port]]. The
               default hostname is "localhost".
    
    
    

    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 load.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 is on the list of things to fix in the future, so don't despair.
           It involves magic cookies.
