[ale] sed question

[David S. Jackson]

How would I solve the following problem:

]$ for i in `cat sample.txt|sed -e 's/ /\ /g'; do
> echo $i
> done

where sample.txt is a simple text files with words and sentences
and spaces between the words.  If I substitute an underscore

]$ for i in `cat sample.txt|sed -e 's/ /_/g'`; do  
> echo $i
> done

then the text comes out as I want it, except that there's an
underscore where I want a space.  However, when I try to add an
escaped space so the shell will leave it alone, the escaped space
never makes it to the echo statement (I guess), and I wind up
with one single word per line.

What's the way around this problem?

TIA!
