How to do an automatic commit after successful merge?

Question

I use this command:

git merge --commit  -m="Automatic commit" --progress my_branch/master
if [ $? != 0 ]; then
    echo "Merge fail"
fi

The merge was successful and do not produce any conflict.
The git command output is:

Automatic merge went well; stopped before committing as requested
fatal: You have not concluded your merge (MERGE_HEAD exists).
Please, commit your changes before you can merge.

Why it show: stopped before committing as requested? I want it commit if do not exist any conflict.

Any idea to make it automatic?

Answer 1

 stopped before committing as requested

That message should only happen when using the --no-commit option.
As illustrated in "Mastering Git subtrees", a git merge --squash would also produce the same message.

So unless (perhaps) you might have a merge already in progress, you should not see that message.
