Ya. To do what I needed (tweak the 9th column, not the last one), perhaps -a or -F would do that in a one liner? I'm not good with those yet.

j

perldoc perlrun

      -a   turns on autosplit mode when used with a -n or -p.  An implicit
           split command to the @F array is done as the first thing inside
           the implicit while loop produced by the -n or -p.

               perl -ane 'print pop(@F), "\n";'

           is equivalent to

               while (<>) {
                   @F = split(' ');
                   print pop(@F), "\n";
               }

           An alternate delimiter may be specified using -F.
