Cygwin – Linux Distribution on windows

Open Source tools which provide functionality similar to a Linux distribution on Windows. It is a Windows command line on steroids which runs useful Linux Unix commands. The core part is the Cygwin library which provides the POSIX system calls and environment these programs expect. Cygwin allows easy porting of many Unix/Linux programs without the need for extensive changes to the source code.

It consists of two parts:

  • A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
  • A collection of tools which provide Linux look and feel.
