If you ever need to play a wave file (*.WAV) from the DOS/Command
Prompt (from a .BAT/.CMD file for example), you can use the following command:
Windows 95:
mplayer.exe /play /close <wave file>
Windows NT:
mplay32.exe /play /close <wave file>
For example:
Windows 95:
mplayer.exe /play /clos c:\windows\media\ringin.wav
Windows NT:
mplay32.exe /play /close c:\winnt\media\ringin.wav
