Meanwhile I started with awk. So on the similar lines I am trying to evaluate
awk o/p to var.
start=2
len=10
var=`awk <"$1""myfile" '{print substr($0,$start,$len)}'`
echo $var
After executing, I am getting awk error.
If at the place of $start & $len, I put 2 & 10 resp, it works.
Where am I making a mistake?
