Tried this but it isn't working as I thought.

CODE

awk '{
  if(/^host/)
    {host=$0}
  else if (/^cups/)
    {pkg[$0]++}
  {for (i in pkg) print host" "i}
}' $1 

RE: host and package on one line

Hi

If one host's cups are always occur consecutively, I prefer to not stack up the data, just to delay it :

CODE --> command line

awk 'p{printf"%s%s",p,/^host/?ORS:OFS}{p=$0}END{print p}' $1
