Elixir System.cmd Lock

Question

I would like to create a system that automatically extracts github repositories using

System.cmd("git",["pull", link])

Does this command block? If I start it at the same time in many actors, can I always get as many actors (or at least a socket restriction for the system)?

If it’s not, did it happen?

Erlang and, therefore, Elixir IO does not block, so the IO of one process does not affect other processes at all. Joe Armstrong describes this in a blog post :
