This is a job for the shell IFS variable.  Just set it to
contain a single newline, and then each line will be
treated as a single input field.   Like this:

IFS='
'
for f in `cat t1.txt` ; do echo $f ; done

Or like this, without cat:

IFS='
'
while read f; do echo $f; done < t1.txt


You may need to restore IFS to its default, depending on
what else you do in the script.
