upsc(8)

NAME

   upsc - example lightweight UPS client

SYNOPSIS

   upsc -l | -L [host]

   upsc ups [variable]

   upsc -c ups

DESCRIPTION

   upsc is provided as a quick way to poll the status of a UPS server. It
   can be used inside shell scripts and other programs that need UPS data
   but don't want to include the full interface.

OPTIONS

   -l host
       List all UPS names configured at host, one name per line. The
       hostname defaults to "localhost". You may optionally add a colon
       and a port number.

   -L host
       As above, list all UPS names configured at host, including their
       description provided by the remote upsd(8) from ups.conf(5). The
       hostname defaults to "localhost". You may optionally add a colon
       and a port number to override the default port.

   -c ups
       Lists each client connected on ups, one name per line.

   ups
       Display the status of that UPS. The format for this option is
       upsname[@hostname[:port]]. The default hostname is "localhost".

   variable
       Display the value of this variable only. By default, upsc retrieves
       the list of variables from the server and then displays the value
       for each. This may be useful in shell scripts to save an additional
       pipe into grep.

EXAMPLES

   To list all variables on an UPS named "myups" on a host called "mybox",
   with upsd(8) running on port 1234:

       $ upsc myups@mybox:1234
       battery.charge: 100.0
       battery.voltage: 13.9
       battery.voltage.nominal: 13.6
       . . .

   To list the UPSes configured on this system, along with their
   descriptions:

       $ upsc -L
       apc: Back-UPS 500
       ppro2: Patriot Pro II

   To retrieve the status for all UPSes connected to mybox, using
   Bourne-shell syntax:

       $ for UPS in `upsc -l mybox:1234`; do
           upsc $UPS ups.status
       done

   To list clients connected on "myups":

       $ upsc -c myups
       127.0.0.1
       ::1
       192.168.1.2

SCRIPTED MODE

   If you run this program inside a shell script or similar to get the
   list of devices and variables, you should only consider using output
   from stdout, not stderr.

DIAGNOSTICS

   upsc will either print a list of UPS names, a list of all supported
   variables and their values on the UPS, or an error message. If you
   receive an error, make sure you have specified a valid UPS on the
   command line, that upsd(8) is really running on the other host and that
   no firewalls are blocking you.

HISTORY

   Earlier versions of this program used the upsfetch library and UDP
   sockets to talk to upsd. This version of upsc uses the new upsclient
   library, which only talks TCP. This is why upsct no longer exists.
