But you will end up with problems with the number of arguments on a
command line if multi_line_file is too large.
How about:
cat multi_line_file | xargs
Note that the default command for xargs is echo
Or, to avoid a "useless use of cat" award (see
http://partmaps.org/era/unix/award.html):
xargs < multi_line_file
