awk - filtering data by if --> into an array
Hi

my data is in csv-format ...
Code:
...

13/08/2012,16:40,305.50,5.00,3,2,2,1,12360.0,322
13/08/2012,16:50,319.90,3.80,3,2,1,0,2280.0
13/08/2012,17:00,326.10,3.50,3,2,1,1,4380.0,321
13/08/2012,17:10,333.00,3.80,3,3,1,0,2280.0

13/08/2012,18:20,340.70,1.60,3,3,1,1,6840.0,331
...

here a awk-script changes the date and time-format
Code:
cd $home
        if test -f "$f" 
        then
        awk '{FS=",";  print  substr($1, 4, 2) "/" substr($1, 1, 2) "/" substr($1, 9, 2) "-" $2  "\t" $10}' $home/$f > index.txt
        else
        DAT=$(date +%Y%m%d)
        printf "$DAT - Datei $i nicht vorhanden" >> "/home/imp/Desktop/Bachelor_Projekt/APS3321/Messdaten/Logfiles/Log_$(date +%Y%m%d).log"
    fi

Code:
08/13/12-16:30  322
08/13/12-16:40  422
08/13/12-16:50  
08/13/12-17:00  321
08/13/12-17:10  
08/13/12-17:20  
08/13/12-17:30  332
08/13/12-17:40  
08/13/12-17:50  331
