How to process ">>" horizontally in bash

Question

When I try the command

 dig +short ns kinoafisha.info >> text.csv

it gives the result

ns2.kinoafisha.info.
ns1.kinoafisha.info.

Is it possible to get results like

ns2.kinoafisha.info. , ns1.kinoafisha.info.

I got no clue... Please suggest

Answer 1

Try this with awk

dig +short ns kinoafisha.info | awk -v RS='' '{gsub("\n", ", "); print}' >> text.csv

Answer 2

Try:

dig +short ns kinoafisha.info | tr '\n' , >> text.csv

If you need spaces around the ,, you can add these as follows:

dig +short ns kinoafisha.info | tr '\n' , | sed 's/,/ , /g' >> text.csv
