The manual explicitly lays this out as something you can do: -n Give each name the nameref attribute, making it a name reference to another variable. That other variable is defined by the value of name. All references, assignments, and attribute modifications to name, except those using or changing the -n attribute itself, are performed on the variable referenced by name's value. The nameref attribute cannot be applied to array variables. It results in $ declare -p foo bar declare -n foo="bar" declare -i bar
