the options -atime, -mtime etc. do not accept an argument of the type "Apr", so you cannot do what you want in this way. These arguments expect an integer, which specifies the age of the file in days or minutes. See man find for more info, or http://www.softpanorama.org/Tools/Find/find_mini_tutorial.shtml Chris
