Det finns ingen felhantering av argument, kommer förmodligen inte heller, så se till att köra scriptet enl. nedan.
Använd såhär:

$ ./genRRDbars.sh
Usage: ./genRRDbars.sh [OPTION] [ARGUMENT]...
-c YYYY+YYYY
Compares total per month of two specified years
-d YYYYMM
Total per day, specified month
-h
Display this help
-m YYYY
Total per month, specified year
-t YYYYMMDD
Total per hour, specified day
-y YYYY
Total specified year and five years back in time

#Generate power consumption month, every hour for current and the first for last month

*/59 * * * * /home/pi/bin/genRRDbars.sh -d $(date -d "-0 month -$(($(date +\%d)-1)) days" +"\%Y\%m")Gör man så slipper man ändra något i crontab, observera att alla filvägar i "User Variables" inte kan vara relativa (tex. ~/rrd/elmatare.rrd) om man använder crontab.
