You certainly know exactly what you want. perldoc -f readdir # how to read a dir and grep for files only perldoc perlvar # for an explanation of @ARGV and processing of command-line args. perldoc -f sprintf/printf # For a way to nicely format some headers or perldoc -f format # For an alternative way to format some headers. See how you get on then, if your stuck, mail the list showing what you've tried and your'll get more pointers then.
