One shouldn't use ‘export’ here, unless, of course, the intent
is to pass this variable to all the processes started from
within that shell. Plain $ i=value will do, as in:
$ (i=world ; printf 'Hello, %s!\n' "$i")
Hello, world!
$
(The parentheses there ensure that the variable will be used for
this command line only and will not linger.)
