Fala Thiago,
rápido e simples:
$ paste -s base.txt
Julio,
Muito Obrigado,
Só para documentar, olha a diferenca no tempo... :
wc -l base.txt
162 base.txt
Com paste...
time paste -sd ' ' base.txt
real 0m0.002s <=== 6x mais rapido ;-)
user 0m0.000s
sys 0m0.000s
Com awk...
time awk '/==/{printf "\n"$5" "} !/==/{printf $NF" " }END{print " "}'
base.txt
real 0m0.012s
user 0m0.000s
sys 0m0.000s
