[ALUG] Copying lots of hidden files and directories - how?

If I want to copy a hierachy of files and directories which include a lot of hidden files (and directories) i.e. ones which start with '.' what is the easiest way to go about it? I know one approach is to use tar but it would be easier if I could simply 'cp -R x y' and copy *everything* in x to y. Is there not a simple way to do this? -- Chris Green (chris@halon.org.uk)
