Setting the IFS (input field separator) environment variable should do
the trick:


tom at t40:~$ for i in `cat foo` ; do echo $i ; done
foo
bar
bar
Barbar
is
no
foo
he
is
Celeste's
husband,
and
an
elephant
tom at t40:~$ export IFS='

tom at t40:~$ #there was no space after the first ', only a linebreak
tom at t40:~$ for i in `cat foo` ; do echo $i ; done
foo bar bar
Barbar is no foo
he is Celeste's husband, and an elephant
