awk --> math-operation in a array
Hi

main object is categorize the difference of data-values (TLUFT02B - TLUFT12B).
herefor i read out data-files which are named
acording to the timeformat yyyymmddhhmm.
Code:
WR030B      266.48 Grad      0
WR050B      271.46 Grad      0
WR120B      268.11 Grad      0
WV030B        2.51 m/s       0
WV050B        3.47 m/s       0
WV120B        4.82 m/s       0
TLUFT02B      7.82 °C       0
TLUFT12B      6.87 °C       0
NSCHLB        0.00 mm        0

i try to read out the data and write it in a new file, with ...
Code:
#!/bin/bash
a=$(date --date '1 month ago' +%m)
e=$(date +%m)
y=$(date +%Y)
home=$HOME/Desktop/Messdaten/METE
cd $home
fpat=$(ls `eval echo $y{$a,$e}*` | tail -n 1584) ## 1584 Dateien entspr. 11 Tagen
for i in $fpat
do
      if test -f "$i"
      then
         Dy=${i:2:2} Dm=${i:4:2} Dd=${i:6:2}
        UZh=${i:8:2} UZm=${i:10:2}
        res=$(awk '{A[$1]=$2}END{print A["WV120B"], A["WR120B"], A["NSCHLB"], A["TLUFT12B"], A["TLUFT02B"]}' OFS='\t' "$i")
       T120=$(awk '{B[$1]=$2}END{print B["TLUFT12B"]}' "$i")
        T20=$(awk '{C[$1]=$2}END{print C["TLUFT02B"]}' "$i")
        printf "%s/%s/%s-%s:%s\t%s\t%s\n" $Dm $Dd $Dy $UZh $UZm "$res" "$T20-$T120"
      else
        DAT=$(date +%Y%m%d)
        printf "$DAT - Datei $i nicht vorhanden" >> "$home/../Logfiles/Log_$(date +%Y%m%d).log"
    fi
done

I want the difference of the values T20 and T120 -- blue!
but in the printf-comand gave me the listed values seperatet by the minus.
Please, can someone give me a hint
thanks in advance,
IMPe

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
