So you keep typing
ls at the Windows command line instead of
tar on your PC? The open source UnixUtils project offers ports of "the most important" GNU command line utilities, including those listed as well as over 100 others. Usually we recommend using the Unix emulator Cygwin to get *nix command line goodness in Windows, but UnixUtils doesn't depend on the whole Cygwin layer to run—they're tried and true Windows executables. UnixUtils is a free download for Windows only. Thanks, Vijay!
