The best way is not to use spaces in filenames; underscores perform
their purpose very well without making things more complicated. :-)

To iterate over files, I would not use `ls`, instead, I would let
the shell do the expansion of * for me, as it has already been
suggested.

Because the file names x iterates contain spaces, be very (!) careful
to assure that the applications you call with these filenames get
the spaces correctly masked, either put the filename in quotes or
substituts " " by "\ ". You would have won nothing when the application
you call with the filename interpretes it as an argument list with
two elements.

for x in *; do
	echo "${x}"
done

Replace the middle line with any program call you want.
