          Using the rename command:



          rename -n 's/./U$&/' *



          • -n only shows what changes will be made. After you verify the changes, run without -n to actually rename the files.


          • s/./U$&/: substitutes the first character (.) with the uppercase (U) of whatever was matched ($&).

          Example:



          $ ls
          bar foo
          $ rename -n 's/./U$&/' *
          rename(bar, Bar)
          rename(foo, Foo)

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
