Cygwin is a Linux-like environment for Windows. It consists of two parts:
- A DLL (cygwin1.dll) which acts as a Linux emulation layer providing substantial
Linux API functionality.
- A collection of the popular GNU development tools.
Cygwin runs on all modern 32 bit versions of Windows, except Windows CE.
This includes Windows 95/98/ME/NT/2000/XP/Vista.
Cygwin is distributed at no charge for commercial or non-commercial use. For more information
read the
Cygwin licensing terms.
