Two-file processing in awk
I have file :
result.txt
Apple fruits 10 20 30
Car vehicle 40 50 60
Book study 70 80 90
Assume here 2nd column is a feature, 3rd column is Min, 4th column is Median, 5th column is Max
. I have another file config.txt which contains a property for each feature i.e.
config.txt
fruits Max
vehicle Median
study Min
So I want to write a script which shows only that column number for the feature which is defined in config.txt
file.
Expected output:
Apple fruits 30
Car vehicle 50
Book study 70
I am following this link https://stackoverflow.com/a/40206489/10220825. Here what I have tried:
awk 'FNR==NR{arr[$2];next} $1 in arr {var =$2;print var}' result.txt config.txt
I can able to hold the property(like Min, Max, Median) in a variable for the corresponding feature defined in result.txt, but not able to display the column for that variable. Please suggest me an approach on how to print the column for the corresponding column.

You need to map the feature names in the config.txt
file to field indices in the result.txt
file, e.g.
awk '
BEGIN {ind["Min"]=3; ind["Median"]=4; ind["Max"]=5}
NR==FNR {arr[$1] = ind[$2]; next}
$2 in arr {print $1,$2,$(arr[$2])}
' config.txt result.txt
