Lily,

I hate to be the third to reply but I didn't find the first two
responses satisfactory.

That depends what you mean by "nothing".  If bash says "command not
found", then read the FAQ entry:

	Bash says "command not found", but it's right there!

If *truly* nothing happens, then I have no explanation.

That's because Windows does not have C:\cygwin\bin (or wherever you
installed Cygwin) in its PATH environment variable.

Someone with Windows XP will have to tell you how to remedy this.  On
NT the "System" control panel lets you set environment variables.  On
9x you can add something to autoexec.bat.

Cygwin will set the PATH for you when you invoke the Bash shell from
the "Cygwin" shortcut.  But that doesn't help when you double-click an
executable from Windows Explorer.

Hope this helps.

Regards,
David
