Cygwin – command not found

1. Right click on “My Computer” -> Properties -> Advanced ->
   Environment Variables
2. Add a new environment variable, called CYGWIN_HOME and set its value to C:\cygwin
3. Edit the PATH environment variable and add %CYGWIN_HOME%\bin to it (usually separated by a ‘;’).
4. Just click okay, exit any command prompts or bash shells (over cygwin) you may have open, and open it again – it’ll work!

Assumption – this assumes that you have installed cygwin at C:\cygwin. If you’ve kept it someplace else, please modify the above accordingly.
