awk '/nome2/' lista.txt
nome2

awk brings me the name I seek!!

cat lista.txt
nome1
nome2
teste
nome3

know that it is possible in other ways as the use of sed for example!

the more I want to do it with awk

Answer 1

You can do the following:

$ awk '1; /nome2/ {print "teste"}' arquivo.txt
nome1
nome2
teste
nome3

• 1; prints all lines.
• /nome2/ {print "teste"} prints "test" when you find "Nome2".
