ack print matches found in one line on one line not mutiple

Question

Right now ack prints out all the matches separated by a newline. I'd like it so that all matches in one line are also printed on one line... possible?

I can add --with filename which prints out the line number the match was found on and THEN do some other stuff to combine it again but I'd rather not.

my command:

ack -o --with-filename '(route_start_date)"([^,]*)"|(route_end_date)"([^,]*)"|(route_status)"([^,]*)"|(route_name)"([^,]*)"|(PARTNER_GUID)"([^,]*)"' sample.txt

I'd like to see

Answer 1

I'd like it so that all matches in one line are also printed on one line... possible?

cat
sat
hat
