   well, once removed the 'safety' echo, it does some deletions leaving just   
   one file per month even if in an apparent random mode, I think there is a   
   missing slash in dir /b o-n, should be dir /b /o-n   
      
   let me try again, I worked on a copy ;)   
      
   so, with the change it leaves just the first of each month, it's anyway a   
   valid solution, thank you
