Question

So I have got a file which contains lines like this :

Kiss Bea 3 4 5 4
Nagy Katalin 4 5 2 3

I ve tried this:

  read name  
        while read var1 var2 var3
        do
            if [ $name == $var1 ]
            then 
                echo $var3
            fi
        done < test.txt

name="Kiss"
so var3= 3 4 5 4 here

My problem is that I can’t put thoose numbers (which are in var3) into different variables because I need a script that writes out the average of those numbers.

Answer 1

One way like this in bash:

read name
while read var1 var2 var3
do
    if [ $name == $var1 ]
    then
        echo "scale=2;(${var3// /+})/4" | bc
    fi
done < test.txt

Replaced all the spaces with ‘+’ in var3 and the average was done using the bc command.
