Executing commands on PATH by default.
Created by: skylerberg
Instead of having
exec spawn a subprocess we should use that logic when the user enters a non-builtin command. For the sake of usability on redox we need to make sure that it uses PATH properly to find commands on the system.
Once we do this, we will be able to a remove all the commands we have that should not be builtins. We will also be able to to add more commands into redox by putting them wherever the equivalent of /bin ends up.
