I add #!/bin/bash at the beginning of my script
my script is in /home/nut
the user nut is owner
I run my script with sh /home/nut/alert_ups

I try running upsmon in debug mode with "upsmon -DDD".
I have a denied permission when the file ups.log is created

I create it and I add nut owner

and all is OK


I'm going to continue my setteings

PS : sorry for my bad english

2007 effectively ....

indeed, time passes too quickly!

 my script: very simple

if I run it manually I have no problem

# write to a specific log file
date=$(date +"%F %T")
echo "$date >> UPS ALERT, shutting down in a few seconds..." >>

is the above your complete script?
if so, you should really add a header like:

don't forget that this will be run from a program, which may be different
that running from a shell.
next, how do you manually call your script? ie "sh myscript.sh" or simply
in other word, are the executable bits set?

your problem here may be that the NUT user (the one running upsmon) doesn't
have the right privileges to access to your home, where your script is
in this case, you should put it in a more neutral location, like

to get the exact issue, try running upsmon in debug mode (after having
stopped it), using "upsmon -DDD".
and generate a power failure. have a look at the same time at upsmon output
to see what's going on...
my guess is that it will be solved by either of the above fix (location,
exec bits, header line for interpreter declaration)

I have restart upsmon after each modification in upsmon.conf


I also have question about

POWERDOWNFLAG /etc/killpower

When UPS is on LB, it stops and when it restarts

I don't have any file killpower ?

this one gets cleared (removed) when upsmon restarts.
