I am trying to create a Variable from value of another variable and trying to store value into the created variable in Shell Script. For Example:
Let there is a existing variable i=1

I am trying to store value in var_$i

I have tried:

i=1 "var_$i"='true' echo "$var_1"

Output: bash: var_1=true: command not found

AND

i=1 var_indirect="var_$i" ${!var_indirect}='true' echo "$var_1"

Output: bash: =true: command not found

I am expecting:

echo $var_1 will give the output true
