title: In bash, cp does copy dot files while using wildcard? Which option should I use
body: <p>When I use 
      cp -r source dest, 
  the dot files as in .gitIgnore or any .xyz are ignored. When I use 
      cp -r source/.xyz dest, 
  then they are copied. Which option with cp can copy all the files including the dot files while using the wildcard *?</p>
