Unix on Windows

While this may be useful to you, really this is just an excuse to link to http://www.scl.com/products/mks/grep-for-windows

There are plenty of times when using a beloved unix/linux/gnu tool on a windows platform is just the right thing to do. When this happens I figure you have a few options :

• GNU utilities for Win32 - http://unxutils.sourceforge.net/ - these are some perfectly good builds of tools/utilities such as ls/grep/sed/gzip/find that are statically linked, so there is no need for extra dll's or installation.
• When you need more than just some tools then something like Cygwin may be more appropriate http://www.cygwin.com/ . This will provide a build environment so you can build your own stuff on windows.
• Finally, when you need the job finished, need support for lots of obscure unix API's or need supported versions of Unix utilities then MKS toolkit is what you're after. http://www.scl.com/products/mks
