you should save IFS somewhere, anyway.
you might do
[...]
OLDIFS=3D"${IFS}"
IFS=3D'
'
for i in "`command`"; do
IFS=3D"${OLDIFS}"
echo "${i}" | read one two
othercommand ${one} more arguments -paramaters ${two}
IFS=3D'
'
done
[...]
in bournish shells. i am a zsh user, so perhaps this won't work in
/bin/sh...
arguments should be parsed as expanded text, so it should not really
matter if you use them as subsequent arguments. the technique with
echo'ing the value through read splits it into the two variables.
does this make sense?
