if you're going to go that route:
it's safer to replace the spaces with underlines so 's/ /_/g'
the find/xargs will still choke on files with spaces in the names,
however the syntax to work with that is find ... -print0 | xargs -0 which
then uses NULL as the file name delimiter
so: find <path> -type f -print0 | xargs -0 rename 's/ /_/g'
add -v to rename so it will print out the names of the files it changes
use -n to not actually rename, but to show what it would have done
