Hi all!

my first post here, so mods -- if this should ideally be in the scripts section, please move there. Thanks!

I have data in the following format:

key1:value1 key2:value2 key3:value3
A
B
C
D
key1:value4 key2:value5 key3:value6
A1
B1
key1: ...

value3, A B C D
value6, A1 B1

Try:

awk '/key3/{split($3,a,":");printf "\n"a[2]", "}!/key3/{printf $0" "}END{printf "\n"}' file

Thanks, bartus11! Worked perfectly
