What does “git commit -vam ” accomplish?

Question

I would like to ask what does the command \"git commit -vam \"message\" \" accomplish, because I have seen no difference with the command \" git commit

Answer 1

As per the git-commit documentation, the "v" option causes the command to be verbose.
The important change with "-vam" is that the "a" option make

git add -u

before git commit.
