upsc - example lightweight UPS client
upsc -l | -L [host]
upsc ups [variable]
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.
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.
As above, list all UPS names configured at host, including their
description provided by the remote upsd(8) from upsc.conf(5).
The hostname defaults to "localhost". You may optionally add a
colon and a port number to override the default port.
ups Display the status of that UPS. The format for this option is
upsname[@hostname[:port]]. The default hostname is "localhost".
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.
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
. . .
To list the UPSes configured on this system, along with their
$ upsc -L
apc: Back-UPS 500
ppro2: Patriot Pro II
To retrieve the status for all UPSes connected to mybox, using Bourne-
$ for UPS in ‘upsc -l mybox:1234‘; do
upsc $UPS ups.status
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.
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.
