Do you want the powerful Unix/Linux shell right on your windows desktop? It is very easy to get it working, just install Cygwin. Cygwin is a Linux-like environment for Windows. It enables you to have most powerful Linux commands and shell programs like bash shell, vim editor, grep, OpenSSH server & client and much more.
After installing Cygwin it will put an icon on your desktop to run the shell. A small tip to access your hard drive partitions is found under the directory /cygdrive/ with every partition found with its name (c, d, …) .
