Once installation is complete the MSYS environment is available for use

In the MSYS shell window you may enter MinGW/MSYS commands as well as Windows commands

In the MSYS shell your default directory will be /home/username which translates to c:\msys\1.0\home\username

From within the MSYS shell, your C:\ directory is /c/ and similarly, D:\ maps to /d/

Entering notepad at the prompt will start the windows notepad program. You can enter your program here. Be aware that notepad will append .txt to your file which you will have to correct.

It is recommended that you use either vi or the Notepad Plus windows program.
