Ok, so the command you want to issue, for $i == 2, is:
echo $v2
So construct that string:
shcmd="echo \$v$i"
or
shcmd='echo $v'$i
The result of that is that the variable "$shcmd" contains the string:
echo $v2
Then "eval" that command (which takes a string and runs it as a shell
command):
eval "$shcmd"
So your loop would look like this:
for i in 1 2 3
do
shcmd="echo \$v$i"
eval "$shcmd"
done
Cheers,
