-delete
              Delete files; true if removal succeeded.  If the removal failed,
              an  error message is issued.  If -delete fails, find's exit sta‐
              tus will be nonzero (when it eventually exits).  Use of  -delete
              automatically turns on the -depth option.

              Warnings:  Don't  forget that the find command line is evaluated
              as an expression, so putting -delete first will make find try to
              delete everything below the starting points you specified.  When
              testing a find command line that you later intend  to  use  with
              -delete,  you should explicitly specify -depth in order to avoid
              later surprises.  Because -delete  implies  -depth,  you  cannot
              usefully use -prune and -delete together.
