Re: [Help-bash] Is there a way to make variables used in a sourced script local to the script being sourced, so that the variables will not be available in the script where the "source" command is called?

What are you trying to do exactly? There's not a lot that can be done about
that since there's only one namespace.

In a very large program there might be a file that sources another and then
calls a function to clean up unused functions (and itself) with `unset -f` when
finished with them. That's about the best you can do.
