Am I right? intofywait should be event-driven where watch would run the specified command at intervals so it would be a matter of chance to catch a momentary event. You might also be able to see what files had been accessed most recently with 'ls -lurt' in the directory which will sort the most recently accessed file to the end of the list. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
