I am not a shell expert by any stretch of the imagination.

I found another alternative when trying to do this.

   while read line
   do
      something with $line
   done < "$some_file_name"

My understanding is that it basically hooks up the file contents as standar=
d in
to the read call.  This actually splits the line using the IFS characters as
delimiters (as would happen, I think, in the above example as well) and puts
them into as many variables as are supplied.  I just didn't have any spaces,
etc in my input.  However, look at the man page it appears that if you just
don't supply any variable names after 'read' then the line will be present =
in
$REPLY.  I haven't tried this though.
