Found the answer in this link:

Code:
$ cat testdata | awk 'ORS=NR%5?" ":RS'

Code:

Minor adaptation to Radoulov's awk:
Code:
awk 'ORS=NR%5?FS:RS' file

Wonderful! But I can't clearly understand what's going on here. Can you explain a bit more, please?
Code:
ORS=NR%5

--Nevermind, I understood
Code:
ORS=NR%5?FS:RS

If NR%5 = {1..4}, then ORS=FS
if NR%5 = 0, then ORS=RS

Awesome... Smilie
