+To also process subdirectories, add the ''-r'' (or ''-recurse'') option
+To only process files with a .jpg extension, use ''-ext jpg'' (case insensitive)
+Example to rename all ".DNG" files in the current directory and it's subdirectories (without moving them):

+  * ''<nowiki>%%02.c</nowiki>'' : Numbering in case of duplicates: "00", "01", etc.
+  * ''<nowiki>%%e</nowiki>'' : extension
 After the Exif rename, remove the unneeded "-v00" extension in the destination:
-<code>
+<code bash>
 find "$dest" -iname "*-v00.jpg" -exec rename -v 's/-v00(\.jpg)/$1/i' {} +
