Maybe offtopic: Dealing with filenames with blanks in a script

[diego <ddc_prueba@yahoo.es>]

Hello, I know this is nearly offtopic, but need some help on a simple
one line script as didn't find a simple solution through Google.

I'm trying to manage files that have one or more blanks in their names
(I'm not responsible for them being in such *nice* format...). Let's say
I have the files:

test 1
test 2
test 3

I want a script to do some processing on them, let's simplify with a
simple cat:

for i in `ls *`; do cat $i; done


but this will fail as it consider the blank as a separator for next
filename.

Thanx in advance.
