Gow is one of OSS products for MS Windows.
For those who usually use Linux or Mac OS X, command line operations are real pains when they switch to Windows. As we have no choise but to use GUI on it, it would be convenient if we can do some work on a command line.

Over 130 commands

In that case, I used to use Cygwin. But I didn’t like it bacause of its frequent changes of registries and the naming “cygdrive” itself.
If you want to use just commands simply, try Gow.

Gow (Gnu On Windows) is a set of Linux commands, which can be used simply. It is a package consists of around 136 common commands includes ls, wc and wget, serviceable programs such as cvs, scp or putty. Interestingly, it has vim as well .

Gow will be added to PATH so that we can call various commands freely on a commnad prompt window. A “Command Prompt Here” menu will be added to the context menu in Exploler as well. If you use Gow, the command prompt would be more useful tool. As it is simpler than Cygwin, it would be great for the most people.
