Sun Solaris Unix Shell script that adds 2 to a string numeric and checks last value for changes
Question: Currently our Sun E450 could detect room temperature ie ambient (from
"prtdiag -v" and I've observed that it's consistently reporting about 2 Celsius lower
than the general DC room temperature :
# prtdiag -v | grep -i ambie
AMBIENT 19
"date" command in this Solaris 8 box's format is :
# date
Sat May 9 06:06:58 SGT 2009
I'll need a Shell script that run every 1 minute (I'll put this into the crontab as
* * * * * /path/script_name) that will do the following :
I'll need this Shell script to be able to notify/email me when AMBIENT is :
(>= 21 AND there's a change from the reading one minute ago) OR
(<= 20 AND the temperature recorded one minute ago is >= 21)
Above script basically notifies me once only (not repeatedly) when temperature
hits 21 C but if temperature keep going up (at levels above 21 C) it will keep emailing/
notifying me.
This script only notify me once when temperature go below 21 C (but only notify
once and not repeatedly and it will stop notifying if room temperature stays below
20 C)
the script in pseudo codes :
Currentdatetime=yyyymmdd:h
echo RoomTemp + " " + Currentdatetime >> yyyymmdd_outputfile
add 2 to the value given by "prtdiag -v | grep AMBIENT" (call this variable RoomTemp
if RoomTemp equals or exceeds 21
check RoomTemp vs last_temperature recorded in last line of yyyymmdd_outputfile
if RoomTemp equal or exceed 21 AND is higher than last_temperature
email to myemail the value Currentdatetime+" "+":Room temp is now "+RoomTemp
endif
if last_temperature in last line of yyyymmdd_outputfile >= 21 and RoomTemp is <=20
email to myemail the value Currentdatetime+" "+":Room temp now is down to "+RoomTemp
endif
exit

Think there's a problem with outfile :
# outfile="`/usr/bin/date +%Y%M%D`.log"
# echo $outfile
20092705/22/09.log
as the script gave following error when run using "ksh -v scriptname" :
>ksh -v chktemp.sh

Even after I've hardcoded as follows, got another error :
