. And .. whilst opening a directory

When I view the contents of a directory, why is it that the first values are . and .. before printing the actual contents. This isn't necessarily a problem because I have used shift to remove the first and second elements of the array which are . and ..

they have nothing to do with perl if thats what you may have thought. I think '..' points up one directory level, not sure what '.' is for though.

. is the current directory
if you don't have your profile setup right you need to say
./script.pl
instead of saying script.pl because just saying script.pl tells it to look in your path and if . is not in your path it will never find it.

@Files=grep(!/^\.\.?$/, readdir DIRHANDLE);

reads the filenames into an array and eliminates . and ..
