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
