I have a lot NUL files in many dirs, which can be removed only from Cygwin: $ rm NUL I don't fully debug but think this come from 'null-device' variable (which has 'NUL' value by default). To friend native GNU Emacs with Cygwin (and stop creating NUL) I use: (when (eq system-type 'windows-nt) (setq shell-file-name "bash") ;; Workaround for Cygwin shell, when set 'CYGWIN=noglob'. By default 'shell-quote-argument' ;; quoted by double '\' chars this cause failure. (defun shell-quote-argument (argument) (concat "'" argument "'") ) ;; Workaround for Cygwin when 'shell-file-name' is 'bash'. (setq null-device "/dev/null") ) -- Happy hacking! -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
