Launch a system command with stdin/stdout access

Hi @zapateo, you may want to check out Porcelain – porcelain v2.0.3, it has a spawn function that should be relatively easy to use for something like this.

I do agree with @NobbZ overall with respect to this idea though. Use the right tool for the right job. If you already have functioning python scripts for this stuff and there isn’t internal concurrency issues that a port to Elixir would provide clear wins with, I’d consider whether a port like this provides value. If you want to do it for educational reasons then that’s perfectly fine, but if you’re trying to solve problems, consider whether the problem is a good fit for what you have or a better fit with Elixir.
