Replacing URL within multiple txt file with Linux terminal

Question

I have several files. txt

Ex: arquivo1.txt arquivo2.txt arquivo3.txt

Inside these files I have several urls as follows:

https://www.site.com.br/diretorio/
https://www.site.com.br/diretorio/
https://www.site.com.br/diretorio/

I’d like to replace it with:

https://www.novosite.com.br 

That is, a new website address and without the "/directory/"

Answer 1

1 - View the contents of the files cat site.txt https://www.meusite.com/diretorio

cat site1.txt https://www.meusite.com/diretorio

2 - exchange text cat site.txt site1.txt | sed -i’s,meusite.com/directory, novosite.com,g' *

• View the contents of files after changes

cat site.txt https://www.novosite.com

cat site1.txt

https://www.novosite.com
