$ npm install -g git-recursive
Use git-recursive with the same command arguments you use for git.
You can use git-recursive or gitall as command alias.
git-recursive will search for all git repos in the current directory and lower level directories and run the same command on them. If it encounters an error, it will pause for you to acknowledge it.
Nothing to configure. Simple, straight to the point, no hassle.
If the repos you want to work with as a group are not found within the same directory/sub-directories, simply create a new directory and add the desired repos as symbolic links.
