Bash on Windows : What it is ?
How Does It Work ? & Who Won The Game..?

We know that , recently Microsoft announcednative support for Bash shell in Windows 10 .
Weeks after this announcement in microsoft developer conference, windows insider preview was released with this feature.

Bash on windows, or more specifically windows subsystem for linux is different from cygwin because, cygwin make use of linux utilities modified and compiled for windows.

Developers can also use Cygwin, MSYS, or run Linux in a virtual machine, but all these "workarounds" have their own disadvantages and some serious overload.

Virtual machines, for example, are complete operating systems in themselves, they need dedicated processing power, memory and storage. That's not an ideal solution for developers working from their laptops, as system resources are shared between host and guest operating systems that slows the entire machine down.
