Hi folks,
POSIX says you can use ${10}, ${11}, ... in shell scripts to
refer to the 10th, 11th, ... positional parameters. However for
years I've been convinced that the only safe way to access
positional parameters past $9 was to shift them first. I can't
recall why. I'm wondering whether this is a myth of mine, or if
there is a known portability issue with these. Can anybody help
straighten my brain out?
