This is precisely because grep no longer follows the locale's collating sequence. For instance, even though en_US.utf8 uses the dictionary order (as seen with "sort"), [a-d] is equivalent to [abcd], not to something that would include B and C. So, where is the range specified? -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
