The Windows Subsystem for Linux is bridging the divide between Windows and Linux by letting you run Windows 10 programs directly within a Linux shell. This allows WSL users to create complex shell scripts that affect the Linux distribution and can also be used to execute commands in Windows 10. When you are in a WSL shell, you can execute a Windows 10 program simply by typing its full name. When a Windows console program is executed, its output is displayed directly in Linux rather than Windows. This feature also allows you to use Windows applications as part of complex Linux shell scripts.
