• To complete installation enter the following
  command in the MSYS window
• cp /etc/fstab.sample /etc/fstab
• This command copies the sample file to a new file.

Using MSYS

• 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.
