Verifying a Source Installation There are a number of things that you can do to check if the
installation (make install) went well. The fist is to check where
the system has installed apcupsd using ' which ' and ' whereis '. On
my Red Hat system, you should get the following (lines preceded
with a $ indicate what you type): $ which apcupsd
/sbin/apcupsd
$ whereis apcupsd
apcupsd: /sbin/apcupsd /etc/apcupsd /etc/apcupsd.conf
/etc/apcupsd.status...
