It is possible but i'm not sure what you mean. Do you mean the filename
has spaces like "filename dd mm yyyy"?

I hate bash, but if you have python on your system try this:


#!/usr/bin/python

import os, re

dir = "."

for file in os.listdir(dir):

  m = re.search("(.+)_(\d\d\d\d)-(\d\d)-(\d\d)$", file) 

  if m:

     prefix = m.group(1)
     year = m.group(2)
     month =m.group(3)
     day = m.group(4)
     
     newfile = prefix + "_" + day + "-" + month + "-" + year
     
     print "Renaming file: " + file + " to " + newfile

     os.rename(file, newfile)

  else:

     print "Ignoring file: " + file
