Windows Adds Support For Bash Scripting
 

With the goal of making more developers use Windows, and to help them move their workflows over to Windows, Microsoft has taken the step to enable Bash scripting natively in Windows 10. This will be a new subsystem, and not an emulation layer, with full access to native Windows functions such as the file system and APIs.
