Well... depending on the "structure" of the
data items in the file, you could simply
use a shell script and "read" each line into
3 distinct variables and simply "echo" the single
variable to a new file. Again, I'm also not
exactly sure if you also wanted to strip the
first variable from the source file but you
could do somthing like...

#!/bin/sh

while read first second third
do
echo $first >> ./new_file_1var
echo $second $third >> ./new_file_2vars
done < ./source_file_3vars

exit 0

Again, this assumes the data in the source file
contains no spaces in the data items themselves
only whitespace separating data items.

__________________________________________________________________________________________________________________________________________________

NAME

       lreplace - Replace elements in a list with new elements

SYNOPSIS

       lreplace list first last ?element element ...?
_________________________________________________________________

DESCRIPTION

       lreplace  returns a new list formed by replacing one or more elements of list with the element arguments.  first and last specify the first
       and last index of the range of elements to replace.  0 refers to the first element of the list, and end (or any abbreviation of it) may	be
       used to refer to the last element of the list.  If list is empty, then first and last are ignored.

       If  first  is  less  than  zero, it is considered to refer to the first element of the list.  For non-empty lists, the element indicated by
       first must exist.

       If last is less than zero but greater than first, then any specified elements will be prepended to the list.  If last is  less  than  first
       then no elements are deleted; the new elements are simply inserted before first.

       The  element  arguments specify zero or more new arguments to be added to the list in place of those that were deleted.	Each element argu-
       ment will become a separate element of the list.  If no element arguments are specified, then the elements between first and last are  sim-
       ply deleted.  If list is empty, any element arguments are added to the end of the list.
