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. > When I double-click on the helloworld.exe icon on Windows Explorer, I get > an error prompt: > > "This application has failed to start because cygwin1.dll was not found. > Re-installing the application may fix this problem." 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.
