Create variables with dynamic index in bash

My code should work with #!/bin/sh
Is there a method how to declare a variables in loop with iteration number?
CODE: 

n=0
somestring="asdf asdf"
while [ $n -le 10 ]
do
    "var$n"="$somestring"
done

# now it is possible to call variables var0, var1, var2,...
>> echo $var2
asdf asdf

Thank you for answer!

Solution

  • You can use export : 

    while [ $n -le 10 ]
do
    export "var$n=$somestring"
    n=$((n+1))
done

    Or eval :

    while [ $n -le 10 ]
do
    eval "var$n=\"$somestring\""
    n=$((n+1))
done
