Unix Tools in Windows

It is often helpful to be able to run Unix tools on a computer that is running Windows as its operating system.  See also Virtualization and Emulation.

• ActivePerl (ActiveState) – for running Perl scripts in Windows

• Cygwin - "a Linux-like environment for Windows" (usually requires access to source code of the program you want to run within Cygwin)

• Explore2fs - for accessing ext2 and ext3 filesystems through Windows

• GnuWin32 – "provides ports of tools with a GNU or similar open source license, to MS-Windows (Microsoft Windows 95 / 98 / ME / NT / 2000 / XP / 2003 / Vista / 2008)"

• Subsystem for Unix-based Applications (SUA) – part of the “server” class of Microsoft operating systems, including Windows Server 2003 R2, and Vista Enterprise and Ultimate

• UnxUtils - GNU utilities for Win32 - "only depend on the Microsoft C-runtime (msvcrt.dll) and not an emulation layer like that provided by Cygwin tools"

• UWIN (AT&T Research) – "allows UNIX applications to be built and run on Windows XP/2000/NT/ME/98/95 with few, if any, changes necessary"
