Heroku - Command problem - git push -m master

Good afternoon.

Then someone can help me with a problem in the GIT and HEROKU process.

'-m' is not being recognized when I perform the following command.

$ git push -m master

I made the following commands and the following error appeared:

I also ran the command below:

$ git push --m master

However, another error occurred:

(venv) gabriel@gabriel-Aspire-F5-573:~/Área de Trabalho/Curso/venv/projetofinal2$ git push --m master
fatal: 'master' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
