Handy for the times when you've changed the name of a module or moved it to another folder and Terraform tells you something like:

Plan: 47 to add, 0 to change, 47 to destroy.

Given two arguments, current address prefix and new address prefix, this tool will simply call terraform state mv <current address> <new address> once for every pair of resources involved in the plan where the "current" one will be destroyed, the "new" one will be created, and the addresses of both have the same strings following their respective prefixes.

If a module bob is renamed to david:

$ tf_addr_chg.sh module.bob module.david

If a module abc is moved from the root module to module def:

$ tf_addr_chg.sh module.abc module.def.module.abc
