example cat file | awk '/ip/ && NR-1==h_num && NR-2==n{ r=h" "$3; gsub(/[,"]+/, "", r); print r } /"host_name"/{ h_num=NR; h=$3 } /"name"/{ n=NR }' > new_file

@jango, this example cat file | awk ... is bad practice. Don't take that habit. Use awk '/ip/ && NR-1==h_num && NR-2==n{ r=h" "$3; gsub(/[,"]+/, "", r); print r } /"host_name"/{ h_num=NR; h=$3 } /"name"/{ n=NR }' yourfile > new_file. Besides, file is abstracted, you should specify your own actual file name
