Cygwin is a POSIX-compatible programming and runtime environment that runs natively on Microsoft Windows. Under Cygwin, source code designed for Unix-like operating systems may be compiled with minimal modification and executed. The Cygwin installation directory has a directory layout that is similar to the root file system of Unix-like systems, with familiar directories, such as /bin, /home, /etc, /usr, /var. Cygwin installs with hundreds of command-line tools and other programs commonly found on a Unix-like system. Additionally, many applications may be installed from a packaging system. The terminal emulator Mintty is the default command-line interface provided to interact with the environment. Cygwin provides native integration of Windows-based applications. Thus it is possible to launch Windows applications from the Cygwin environment, as well as to use Cygwin tools and applications within the Windows operating context.
