Hi Ben, There's a full user guide available on the Cygwin site that you may find useful: http://cygwin.com/docs.html This should offer much more detail than "help cd". There's also a quick-start guide: http://cygwin.com/cygwin-ug-net/ov-ex-win.html Thanks, Phil -- Phil Bull http://www.launchpad.net/people/philbull
