How to add lines of a file and average them
I'm reading in numbers from a file and trying to add them together. Here is the code so far. I know the 1+2+3.... part is wrong. The file has five numbers in it with each number on its own line. The numbers are decimals if that matters. Thanks.
HTML Code:
while read EachLine
do
echo $EachLine
done < myfilename
echo sum=$(( "1 + 2 + 3 + 4 + 5" ))
fi
