Is there a tool that finds words in 2 different text files?
example:
file1.txt
pedra
cavalo
torre
animal
fogo
file2.txt
garoto
animal
festa
humano
fogo
result:
animal
fogo
It is not necessary to be 2 .txt files exactly, but only 2 different texts.
As you have not specified the language, I will offer the simplest solution in bash.
$ grep -f arquivo1.txt arquivo2.txt
> animal
> fogo
The -f parameter tells pro grep to get what will be fetched from the file. So it will fetch all words from arquivo1.txt into arquivo2.txt
