You can use $IFS to tell bash to split on just the line feeds instead of the
spaces....
[mloe@riverbank (1) bashtest]$ ls -l
total 0
-rw-rw-r-- 1 mloe mloe 0 Nov 26 18:42 nospace
-rw-rw-r-- 1 mloe mloe 0 Nov 26 18:42 one space
-rw-rw-r-- 1 mloe mloe 0 Nov 26 18:42 one two spaces
[mloe@riverbank (1) bashtest]$ IFS='

[mloe@riverbank (1) bashtest]$ LIST=$(ls)
[mloe@riverbank (1) bashtest]$ for i in $LIST; do echo "-->$i<--"; done
-->nospace<--
-->one space<--
-->one two spaces<--
[mloe@riverbank (1) bashtest]$
I'm not sure though why you can't just use the first one? IF there are
going to be other fuiles you want to ignore you can use a more restrictive
patter than *. Arn't you just going ot have to do the same with thing with
ls anyway?.
Never the less... $IFS :)
