I want to print the value of variables a1, a2, a3 in for loop in the following program:
a1=this
a2=is
a3=printed
for((i=1;i<4;i++))
do
var=a$i
#w=`echo $var`
e=${var}
echo $e
done
But actually I get a1,a2,a3 as the output not the "this is printed"
So the main question is if I have a variable name(say p1) in another variable(in Q) how will I print the value of p1 from Q?
Thanks,
