I need a way to build variable in this manner:

variable_$i
Inside a for loop i need to create it.
where i goes from 1 to 30..
and then i need to print them on screen with echo $variable_$i
which is the best way to do this?

A simple loop will do:

Code:

i=1
while [ $i -le 30 ]; do
    echo $i
    i=$[$i+1]
done
