When using the 'for i in`, how do you get it to read a whole line in the file?

For example, I have a file 'A' with the following line in it:

$ cat A
Hello World

So when I do
for i in `cat A | awk '{print $1}'

I get i=Hello

But I want it to equal Hello World

Is it possible to do this with 'for i in' ?

use $0 instead of $1 ,
$0 is the whole line argument in awk

use IFS.  In a script you can throw away the value
if you're not needing it later.  On the CLI, you need
to save it

OLDIFS="$IFS"
IFS=$'\n'
for i in `cat A`; do
  echo "$i"
done
IFS="$OLDIFS"
