This will disfunction if the names have embedded white spaces. I happen
to batch rename songs etc. which almost invariably have white spaces and
other horrors. So i use something like

mv "$i" `echo $i|sed -e 's/  */_/g' -e '.....' `

Sed has the advantage you can do several transformations at one stroke,
and fine tune the transformations. Double quotes avoid that the shell
breaks names on white space.
